Mitch,
Welcome to the Forum. I've been using Clifton at 7F7 for awhile now and have been happy. I fly a little less than an hour and when husband is gone, Tim flies me home in his Cherokee - he is also multi rated.
http://www.cliftonaero.com/ I've seen as many as 9 Comanches in the shop. Caveat is no shop is perfect but these guys really try. Everyone that works there is an A&P.
There may be someone in Houston, I just don't know them.
