While I'm on a good thing, I thought I'd keep on going. Another poker room that is on the same network as InterPoker and Totalbet is PokerPlex.
They offer a $50 bonus for 300 raked hands, which comes down to $.16 a raked hand. That's better than the "base rate" I've been finding of $10 for 100 raked hands. So, I coulnd't resist.
I'm currently in the middle of playing through this bonus, and will post up the results when I'm finished.
