I'm housesitting for a freind who has a Mac and I couldn't run the
Pokerstars client. I found
Partypoker had this "Play Anywhere" java client and was up and running with a bonus, and a deposit of $100 from Mastercard, in about 10 minutes.
Played a 10man, $22 and got third (won $40), then played a 10man $55 and got second (won $150). Lost HU with 99 against Q6o allin pf. I think the play was a bit looser that most of by PS SnG's but it's hard to judge from 2 games.
Partypoker = one more great reason not to live in the USA
