For future reference since I assume this is already taken care of:
I had a good experience with Central Texas Avionics (https://centraltexasavionics.com) at GTU, which is pretty centrally located to most of the population in the state. Fair price, quick work, didn't try to gouge me on unnecessary parts or labor. They told me up front my M20J's static system would likely need some replacement parts due to age, but the previous owner was meticulous with maintenance and I think I ultimately spent about $5 on a single hose or screw or some such. I like the "be realistic about the worst case, but deliver the best case" attitude there. Turn around was something like 2-3 days not counting the weekend though they did say the shop didn't have a lot going on at that particular time I took it in (January).
