I was hesitant to get my IR for the very reasons that others have posted. I didn't want to be one of those "occasional" users of their rating that ends up an accident statistic. But after two accidental encounters with IMC, I decided it was time. (Plus, I was tired of my wife telling me I wasn't a "real" pilot.)
I was originally going to do the accelerated course, but scheduling problems arose when the nearby instructor quit. Glad I didn't go that route, because it would have been tough for me. I tried doing it in two months locally, using two instructors; a newly minted CFII for the actual instruction, and my old CFI for the extra hood work. That worked well, flying three times per week. But eventually, I had to take a a month off to do stuff that pays the bills. Ended up scheduled for a check ride 4 months after I started, but rescheduled a few days before because I just didn't feel "ready". (Good thing, because I barely squeaked by when I took the ride a month later.)
I almost ended up having to postpone again, due to intermittent problems with the AP, the TC, and then a fuel gauge, but they all turned out to be the result of a faulty ground issue that was easily resolved. When I finally got my ticket (5 months after starting) I had 60 hrs of hood time (20 of it instruction) as well as another 40 hours of me just shooting approaches VFR on my own, a lot of them late at night. I also had at least 10 hours of ground review with my instructors, even though I had gone through both Jeppesen, Kings, and a weekend prep class.
All in all, I think I spent a little over $10k, but I like to practice a lot. It was worth every penny, because I am convinced that I am a much better pilot now than I was prior.
If I was doing it again, I would've spent less time using the autopilot as a VFR only pilot, and more time hand flying. When I started IFR, I sucked at holding course, altitude, and speed within tolerances. I also wish I would have taken the time to get to know my 430 better. Would have saved me a lot of time correcting for errors made while trying to figure out the GPS under the hood!
