I'm figuring around 6V for the motor, probably 0.5-1A current draw, but what do I know? If any of you have any input on that, let me know. Unless it needs to be 12V (the internet doesn't seem to have many 6V motors) in that case I'd probably go with the small banebots motors or similar.
I think RadioShack still sells small DC brush hobby motors and those motors with a realistic mechanical load can be controlled with the L298 (the integrated module on the SparkFun PCB linked in this topic).

Those motors are usually good to around 6V.

They sell a 9V version but it's more speed than torque, maybe too much speed to gear it down without issues.
