Has anyone trained here?

It's run by a student of De La Riva, so I'd guess the BJJ is good. Any opinions? And any info on how much it costs?

Also, has anyone trained BJJ at Sityodtong in Somerville? Who teaches it? I'm pretty sure I can't afford Sityodtong at this time, but I'd like to know for future references.

Background: I'm in between jobs, so I've got a little extra time on my hands right now. I'm looking to do some BJJ, but I can't do it if it's really expensive. I wouldn't mind trying some muay Thai or sanda if it's part of a package, either.
