Where to go to repair 400A Autopilot?

[Dale Campbell]

I am looking for a good place to get my 400a autopilot also repaired, some where near Penna. The last time I had a problem I sent all my parts to Auto Pilot Central. I was told it was repaired. Each time my avionics shop put it back in, it still did not work. They sent it back a total of 6 times,taking 6 months total. Each time they charged me again. When they finally got it going, it cost me over $8000.00. Had I known that in the beginning I would have purchased a S-Tec. Now it is failing again. I need a closer and cheaper shop. Dale
