BJ Seminars?

Anyone have any thoughts on the BJ Science Seminar Series? I saw a thread about it on Advantage Player, and it piqued my interest. They're coming to LA next weekend, and I'd like to go if it's the real deal. They claim on the website that the seminar goes beyond the regular hi-lo and shuffle tracking techniques. Think it's worth the $800? Any info or advice is appreciated!

Thanks,
Mike
