PokerStars: 100% rake return (120% on $5.50 tournaments).
PokerRoom: 71% rake return (57% on $5.50 tournaments).
Bodog: 100% rake return, unlimited deposit bonuses, but you can't withdraw until you clear the bonuses.

I'm not familiar with PokerRoom skins. You might be able to get a better deal on one of those than on PokerRoom.
