Motor controller?

I really want to be able to control some motors and was thinking of this one at sparkfun: http://www.sparkfun.com/products/9670

The problem is that the Pi does not have digital ports? And the motor require it for control (low/high signal). Is the GPIO on the Pi just plain analog? If thats the case, is there a addon that could transform signal from the Pi to the motor digitally? Or is there a motor that supports the Pi's GPIO?

You can also consider this driver:

Also? Is the linked motor a go or no-go? :D

You've got things the wrong way round http://elinux.org/RPi_Low-level_peripherals
The RPi only has digital IO, it doesn't have any analog IO (ignoring the PWM used for audio output ;) )
