Letting us know which country you are in for a start would help (I'm guessing the US), then which state etc!
In Europe and indeed much of the rest of the world 3G/GPRS works well most places and is of the order of $1/MB. If you have a 3G/GPRS provider in your area try them. Gives reasonable speed with low latency; very much like a slowish DSL.
