Shit ...I got like 4 totally free checking accounts opened now with the visa/mc check cards attached. Without having to worry about any minimum balance at all is great. Cause you just put the money in that you want to deposit and send it of. So that the bank account stays pretty empty except a few bucks.
Having the different banks seems to have its good points, cause some books seem to process a wider range of cards than others.
The pre paids are the best options though.
