Bingo Mania is a good site. I just started promoting them, but have been playing there for a couple of months now. They have good games. You can download the software if you want and you get at a 200% first deposit bonus. You get at least 50% bonus on every other deposit. They also offer days where you get up to 200% bonus. I really like playing there and hopefully I will be successful in promoting them. U.S. players are welcome and they have Ewalletxpress, 900 Pay and EcoCard as a good U.S. deposit methods.
I think they also own Mega Nickels Bingo as well.
