I have bought into Titan Poker for $101, using a pokerlistings referral. Titan is another iPoker skin, so it's essentially the same as VCpoker. There is a nice $50 up front bonus via pokerlistings ($101 minimum deposit), plus 200% up to $600 in bonus dollars. I'm not sure of the cashout requirements for the $50. There are also some attractive WSOP freerolls for pokerlistings players, which was the main reason for signing up.
The bonus dollars cash out rather slowly compared to VCpoker, so I won't be spending much time trying to play them through.
