Thanks!  I was thinking about using that one but like you said I'm not sure about the current.  I got the larger of the motors because for my application the motors cannot stall so I figured I wouldn't need to worry about the stall current right?

Hello, I would like to control 4 motors independently.  I am planning on using motors from VEX 2-Wire Motor 393 (http://www.vexrobotics.com/products/accessories/motion/276-2177.html) without the controller module things.  I need to be able to vary the magnitude of the motors independently of each other and also that means be able to reverse the direction of the motors.  I noticed that Stall Current:4.8A and Free Current:0.37A.

Basically my question is what should I use to do this?  Do I need Motor Drivers or Motor Controllers or what?  If someone could recommend a board for the motors I linked above that would be awesome!!!
