I play on Lock Poker and I really like it. It's not anonymous, which is nice because you can take notes and use a HUD. I also like that it's a good mix of regs and fish. My fiance uses Bovada, and depositing money is so much easier on Lock than on Bovada.

The only thing I don't like is that their servers can get overloaded every once in a great while, so you might have a burp in your connection or the whole tournament comes to a hault cause everything has stopped working.
