H Bridge Bigger Motor

Hello, i am upgrading the drive terrain of my robot. I bench tested the new motors and they draw about 2.3 amp at 12 volts each. what is a good h bridge that would do the trick? its a two motor drive system. Also i couldn't re find this thread i found, but it was talking about using a 12 volt motor with a h bridge to replace the function of a servo is that possible? i would like to make head ration bullet proof.

Sabertooth 2x5 H-bridge would be a good solution.

Sabertooth with the Kangaroo add on board makes a motor behave as a servo (you also need some kind of input to the kangaroo, potentiometer, encoder, or limit switches if you only care about the end points).

@Mikej As Alan mentioned just use a sabertooth.... I know they are a bit pricey but they are all I use in my robots... Fantastic motor controller...
