I have used Bovada. 5% rebates every tuesday but they charge 4.9% on deposit. Withdrawls and checks are sent within 5 days. You can even play 90 cent bets.

I found sportsbook .ag much better. 8% rebates daily. No deposit fees and many oppurtunities for bonuses for free bets on deposits. One free withdrawl every month but it can take 3-8 weeks to get a check.
