From what I understand party is great if you can play it. There's a lot of sites with decent rakeback and bonuses for non-us players. If you don't play a ton of tables at once (which you probably shouldn't if you're playing 10-25nl) a lot of sites are good. I'd check out bonuswhores and just start jumping from site to site. There's a good guide for that in the online poker rooms forum I think.
