I finally found a cheap school. The instructor, Jeffrey Something 7th Dan, teaches Okinawan karate there. He encorporates bits of Aikido, Judo, Shaolin Gung Fu, and something else. I watched one of the classes yesterday, and he looks like a good teacher. The best thing is it's only $25 a month! And it's a 5 minute drive away, so I can get there easily. I'm gonna start Monday. I'm so happy!
