There are two Stark Avionics. One is in Olney Texas (KONY) which is just NW of Graham. I had my King repaired there. Dr. Stark was very knowledgeable and the prices were not through the roof. You might give him a try. It might be a little further to drive than the metroplex, but he treated me right.
Another shop is Poor Boy Avionics in San Angelo (KSJT). Tom Dufrense is very good and does good work at a fair price. His shop is in Skyline Aviation. He is usually not there until after 4:00 because he does all the avionics on the Customs planes which is based on the airport.
I think either one would be fine.
