Check Yelp.
Seriously. In major metro areas, it's a great resource for reviews.
lol, I just watched that South Park episode.

There is an experienced and trained Comanche instructor is Burnet, TX. Is that close enough? You can also ask over on the Airworthy Comanche forum on Delphi. There are a few hundred Comanche owners over there.
