You may also need a pwm expansion shield of some sort

You mean like the RobotOpen Control Shield, which will allow you to connect to a DSC via the ribbon cable?

You might be able to find an IFI system somewhere, but VEX is your best option there. For some stuff, an R/C controller might work, but it depends on what exactly you're doing, and those can be expensive too.
