So what is the REAL deal with Direct Buy?

Have you or anyone you knew gone to one of their sales pitch sessions? How much is the initiation fee? Are their prices any better than a savvy Internet buyer can get? Is it a scam?
If you bought in do you feel like you were suckered bu some time share sales person?
Their lack of willingness to give out specific info until you have an appointment and a tour with a trained sales agent makes me leery to get close enough to even find out.

So what’s the real deal?
