I did Landmark's entire program (the two weekend courses plus a weekly, multi-month program). I got something out of it, too, but to be honest, it's not cheap - and there's really nothing there beyond what you you'll find in a decent pop-psych book. In the end, I became extremely uncomfortable with the increasing pressure to enroll friends and family, and chose not to continue with it.
