PWM speed controllers cheaper than Victors?

[ProjectZero]

Woah, thanks everyone. Guess I should have done a bit more research first. I tested today and even when stalled, the motors don't seem to pull more than 0.5 amps, and the typical no/minimal load current is 40 mA. I'm looking to go with nighterfighter's sparkfun suggestions - as basic (and cheap) as option 1 is, it looks like it will do what I need it to. As long as I make certain the Arduino can output a PWM signal in the correct range to control it, we should be good.
