Jeff is a really nice guy and super helpful. I really liked interacting with his family during past visits and they did a bunch of work on my buddies C182 years ago. I just found Affordable was just that, affordable and available to get the work done that I need more quickly. Their pricing was straight forward. The more quotes that you have, the more educated you become. Also one shop may recommend a different package or option you didn’t consider. Howard’s at Pomona is another quote worth checking but they are rather pricy and you get what you pay for. Howard’s has a very clean operation and a large hangar from what I’m told and have seen. You could also check out Pacific avionics out of Oregon. While they are tempting due to the lack of sales tax, it’s worth calculating the cost of fuel, engine wear, time and transportation home when you select an avionics shop. As a business owner I just hate wasting a shop’s time creating quotes and not throwing them work but I guess that’s the cost of doing business.
