I just did the 3 day seminar. Made it through day 2. There were essentially 4, 1.5 hour sessions throughout each day. Day 1 was 2 sessions of fluff and 2 sessions of decent info that I pretty much already knew from the limited time I've been on BP. (definitely learned some good stuff though)
Day 2 was 3.5 sessions of self promotion, and about 45 minutes of explaining what seller financing was a some basic, creative financing examples.
Didn't return for day 3.
While I didn't learn everything I wanted to, I am happy I went.
I know this forum naturally hates on gurus...but I do know someone in my local market that did the full course ($25k+) with these guys (among others). It seems as though he is very happy he took the plunge. From what I can tell, he's absolutely crushing. So it's just a matter of wanting to take the time to learn everything yourself, or pay to have it wrapped up in a nice little box for you. Might seem expensive, but if they teach you to do 10k-50k deals like clockwork, it ends up being pretty cheap.
