I finished my monthly $50 on WH yesterday, and won a further $40 (20BB) in the process. So my initial $100 deposit i now up to $260 after just over five table hours of play. Can't complain.
I also recently joined UltimateBet through PokerSourceOnline (see link on the right). I know that UltimateBet is evil (if you don't know what I'm talking about, just google "UltimateBet scandal"), but the bonus is just too juicy. PSO give you $125 once you earn 375 points, which is roughly 250 contributed raked hands. I initially deposited $100, and nearly busted a couple of times before recovering to around $45 and finishing the bonus for an extra $125.
