Meet the Fokkers
I have decided on what brand, and mostly what components at a minimum, which include removing vacuum stuff, engine monitor to replace all old gauges, etc.

With the remaining budget, I'm trying to decide between these two options.

Option 1:
ADS-B in/out (I currently have Garmin 327 transponder and uAvionix tail beacon)
Audio panel (currently have KMA 24)
Com radio (currently have RT-385 nav/com) Very old, and a bit 'hissy' but works for the most part, and has a Nav/CDI, which I already have with the 430w/CDI

Option 2:
Upgrade the 430w to Avidyne 440

Cost for the two options is almost identical.

Thoughts on what would be best option and why?
 
Option 1
I've always said I thought the price for a decent modern audio panel is well worth it. I don't know what they're going for these days but it makes a big difference. does the 327/tail beacon give you both in and out? if so, why spend the money to replace what you already have?

Option 2
you'll def like the upgrade to a modern touchscreen gps, but again if the 430 works..... does the avidyne have a radio built in? if so then you're kinda doing bits of both options....

Option 3
convert high wing to low wing. I vote option 3!
 
Option 1
The 327/tailbeacon is out only.
I use a Stratux for in. Does a decent job but I'm not sure how much I trust the Stratux as the antennae are sitting up on the glare shield with the unit. It's always in the sun, gets pretty warm, etc.
(edited to add) I think there have been reports of the uAvionix units being inconsistent/unreliable.

Option 2
Yeah, the Avidyne has all the functions of a 430, plus the new goodies, so it would replace the 430 com/nav. The old RT-385 needs to be replaced. The area where the lighted numbers are gets really hot, but it is still usable.

Option 3
That has been a possibility on a few occasions. Price negotiation is where it usually falls apart.
We were watching the STOL event at OSH this week, and asked the question why you never really see any low wing STOL aircraft. Our first inclination is ground effect, or maybe obstacle clearance, but I think really it's just that it's nicer to drink beer in the shade at the gravel bar.

New COM and audio panel would be a great upgrade, modern audio panels have a much better noise floor and a whole lot more features. One option for ADS-B in/out would be pairing a GDL-88 with your 327, they can be had fairly inexpensively and will interface with the 430W for traffic display. Certainly a GTX345 or GNX375 are nice options, but you can pick up a GDL-88 for around $1.2k.
 
Kinda depends on the age & condition of the 430. A 430 WAAS in good shape with a perfect screen has some life left in it. A non-waas unit, or one with screen issues, becomes a high priority for replacement.
 
I'm planning on riding my GNS-430W until it dies. They are very robust. Having a reliable #2 NAV/COM is your insurance against a GNS-430W or GPS failure if IFR. A modern audio panel can make future avionics upgrades simpler and adds some nice features. But like you if the GNS-430W dies it turns into an IFD-440. I'm in the same boat with the #2 NAV/COM. Works, but not pretty and the sound is eh?
 
Have you looked at the used market for the second nav/com? Maybe something newer, nicer that got replaced in a full panel upgrade.

I am leaning to the side of, if you 430 is WAAS and working well, start with the other parts until you NEED to do something about the GPS.

The 430w is waas and is in great shape. Not sure of age but they stopped production in 2011 I think, so at least that old. I'd have to go through docs to see if it was new, or used. My thoughts for upgrading it is the apparent limited support life of it, it's declining trade in value, and everyone's rave reviews about the Avidyne.

I'm going with Dynon brand, so I'll likely put in the Dynon transponder\ADSB unit to easily interface with the HDX. Although I'm not sure if others will or won't interface with it.

The Com I'm looking at has no nav, so it wouldn't be a backup nav for the 430. Sad, but true. One of the little things that keep going around in my head. If the 430 craps out, I can use a GPS backup like the Stratux, iPad, phone, etc...unless there's an outage or I'm getting jammed. All happening when I'm IMC...which with my luck, is quite possible lol.

Haven't looked much at the used market yet, as I'm just now getting serious about upgrading.

All great thoughts/replies.
The general feedback seems to be hang on to the 430w for now. I'm sure that will cost me later, as 430 value goes down, and cost of 440 goes up, but, never know. Maybe there will be a sale :lol:

One of my main thoughts, is do the upgrades to the Audio/Com/Transponder while we have the panels out. The 430 to 440 wouldn't need any panels removed or additional wiring (I'm assuming).
 
The benefit of the 430W is that you already own it, and even though the screen is low resolution, you won't be looking at it anyway with the Dynon screen installed.
As for transponder, any ADS-B Out transponder will work find with the Dynon System, but you will need the Dynon ADS-B Receiver to get weather and traffic on the big screen.
Having a 2nd Nav is getting more and more rare. A lot of airplanes are getting panel upgrades that don't even include a single Nav radio. You can use the Dynon GPS to get home safe if the 430 dies.
The used market for the 430W is certainly declining, and the 440 is slowly getting more expensive, but it is a big ticket item to switch. Resale value will increase on the plane with a 440, but not by as much as it costs you to upgrade it.
While it is open, if you don't have a modern audio panel with built-in intercom, I would highly recommend installing a new audio panel with new audio wiring throughout. There is nothing more annoying than spending a lot of money on a panel upgrade and having sub-par audio. The 430 to 440 would not need any additional rewiring unless you have a GTX345 transponder, in which case one wire needs to be switched on the transponder.
 
Jesse just put a new panel in my plane, and did a great job.
 
For comparison, this is the old panelIMG_6810.jpeg
 
Wow - go big or go home. Nice!
 
Damn, this looks like a diffrent plane without a doubt. Good job
 
I like my 440 with ADS-B in/out add-on. But I do as much IFR as possible and on cross country it’s nice to pull up the local weather and have a list of all ATC facilities on my route plus the freq of the destination. I’m sure the Garmin 650 does that too. You would only need to write down the 430W settings and pull that unit and slip in the 440 and program the settings you copied. So it’s just nicer but it doesn’t mean a newish 430W won’t work for another decade.

@GoFly , the panel is beautiful (really!) but you might want to re-think that heavy ring of keys. The load under vibration can cause premature wear of the switch.

Smart advice. There was a car recall because the ignition switch shorted out. The switch design didn’t take into consideration a heavy key ring putting weight on the switch.

Or convert to toggle switches.
