Dream poker was great until I lost all my money at the casino. Good thing it was freeroll winnings and I wasn't able to withdraw it. I would have been peod if it was my money.
Full Tilt is my favourite - Full Contact has a cool table image I might make a deposit there and try it any opinions?
A note on partypoker/empirepoker - I almost fell out my chair playing there. Preflop raises of 240 get called by like 6 people on the table. Literall you cannot see the cardtable past all of the chips. Then after the flop drops some bets 240 again and they get 4 calls. Unbelievable.
Play on these sites if you never want to learn good poker and continually take bad beat after bad beat.
