Check out Sinlapa's Muay Thai Academy. I train submission grappling with Mike Rangel (awesome teacher). We train Mondays and Wednesdays from 8-9:30, and Saturday from 12-2 p.m. It's only 30 bucks a month, or 5 dollars at each training session. The guys there are generally pretty good (I get my ass handed to me). I think you'd really like it.
Oops, forgot to tell you it's at 2819 Hillcrest Drive.
i go here when i can..but the head guy is very knowledgeable, the classes are inexpensive; an they have alot of solid guys to work w/grapple with, a couple'a guys on this board used to train there before they moved out of state. They also have muay thai instruction there as well....
