[solved]Mr Basic

How can I drive the 2 2-amp motors of a Mr Basic robot?
I saw a drivercircuit here: Let's Make Robots - RobotShop Community, but I won't know what relay to use (I'm a beginner in electronics). Would this one work? http://be.farnell.com/jsp/search/productdetail.jsp?sku=4219582
I know there's one for sale at robotshop, but it's overpriced and shipping cost is at least $20.00 :frowning:

What H-bridge could I use, for instance?

Would a L298 motor driver work?

Thank you very much for helping me! :slight_smile:
