Best motor controller for use

I am making a ROV and need to control a 13.5 volt, between 1.68-12.57 AMP dc motor. I am new to unpackaged robotics (done lego and vex) so need some help please.

What is the best way to control this motor?

Motor test specs are on the 2nd to the 6th pages on the pdf below (I own the website)... http://www.percyjacksonmovies.com/Fan%20Motor_10-20965.pdf

Thanks for your help, Kyle King

I want to be able to control the speed and direction as well.

I haven’t used them, myself, but I can’t remember any of the comments I’ve seen others make about Pololu motor controllers being unfavorable.
