The Pacific Poker bonus is a goldmine. I played off and on there for about 3 weeks, cleared the bonus at $50 NL tables and came up with over $800 in profit (though $450 of that was a 7th place finish in their $15k daily guaranteed tournament). I got sick of the slow, buggy software and constant server crashes and eventually cashed everything else out but the players at that site are so horrible, you just need to be patient enough to hit a decent hand and then it's like an online ATM.
