Well.... a good one seems to be at the poker room in casino.net.

30$ after 100 raked hands, another 70$ after another 400 hands. There is NO minimum deposit, nor is there a minimum rake. In other words, $0.03 rakes in 5 card draw count.

I just started playing there today and cleared the first $30. Don't have a great read on play quality, but it doesn't look anything special.
