help finding motor shield for arduino uno

Building my first robot... need help finding the correct motor shield

Hello, this is my first forum post! I'm in the process of building my first robot, and I'm not sure which motor shield to use. It will be a two wheeled autonomous robot that uses an Arduino Uno. I am using 2  1:120 geared motors. The robot will be similiar to the Bliss Robot (http://letsmakerobots.com/node/28477), just with a different ultrasonic sensor. I now of the Instant Robot Shield made by PICAXE, but I'm not sure if this is the best option for my robot.

 

Thank You!
