I am looking to buy a bjj instructional video and was woundering what other people recommend. The ones i'm looking at are the Marcelo Garcia complete 6 dvd set, the Cesar Gracie set, and the Renzo Gracie/Craig Kukuk vid. I've only been doing bjj for a very short time, so need something with good basics in them. Anyone who has seen or own one of these vids, what would you recommend? thanks.
