While I agree with everyone in regards to the quality of instruction available at 10th planet SF and I try to train there when my schedule allows, honestly, the commute is a bitch from San Jose. Especially if you work a schedule that puts you on the road to SF between 4pm & 7 pm M-F because it can take 60-90 minutes just in traffic. BART is about the same when you consider that it takes about 45 minutes to get to the closest BART station (in Fremont on 880 traffic)and another 45 minutes to get to SF on the actual train. I can get to pretty much any area of SJ in about 20 minutes tops.
I don't argue at all about the quality but when you are forced to live by a tight schedule, with family to consider, closer is better.
