The L298 is a good choice, for motors that do not require more than 1A of current, and do not pull much over 2A when stalled.
The board you linked to is more for 600mA normally, and stall current less than 1.2A.
I'd suggest starting with "continuous rotation" servos, and later getting an appropriate rating driver board once you choose the motors you want to use.
If you want to control a lot motors, servos, and also get analog inputs, take a peek at:
Hi there, I am trying to build build a small robot with a few motors. Just something that can do some cool stuff. I am looking for a good way to control the board. I found this one on adafruit
but I am looking to control more than 2 motors. Are there any other methods of controlling them or any other boards?
