SteinAir and Stark
 

I know both of these companies have been praised to death in the past, but I just wanted to add my 2 cents. I have placed several orders from Stein, and he and his staff have always been very helpful with my stupid questions. I just received my Garmin GTX-327 from Stark Avionics and got it very quickly and in great shape (and for a fantastic price). Gotta love this RV community!

Yep, it's true. SteinAir's customer service is very down-home, personal, and outstanding. I didn't actually buy from John Stark, due to reasons unrelated to him or his business, but I found him to be far and away the best avionics vendor when I was shopping around for my avionics. Highly responsive and good prices.

If there's ever an RV Hall of Fame... after Van and Bob Avery are inducted, I'd definitely drive to the Stein Bruch induction ceremony.

Hey, that would make a HECK of a thread...the RVers Hall of Fame.

In fact, we should actually HAVE one!
