Yes, the problem for me is, too many. Don't know which one to choose and the controller could handle that current are way expensive for me unless they mark it wrong in current like Oddbot said 14.8V --> 148V.

If it's 148V, I was looking http://www.robotmarketplace.com/products/roboteq_speed_controllers.html for those blue box controller on bottom hale of the page but they are really pricy. If you don't mind could you help me to point out which one will be the idle for these 2 motors?
