Glen please do feel free to call me Tony. I have been a partner in my airplane since around 1998 or so (really have to look that up. Not sure). I joined two others in ownership who were TWA mechanics. Each has left the area for career changes and are still part owners but do not fly the plane. I have made many upgrades over the years and have the good fortune of flying with a couple of ace mechanics with years of experience wrenching on GA airplanes with Cessna 150 and 172 being their primary experiences. They have performed the upgrades as well as all annuals since my partners moved away.
