It is one of the cheapest gear boxes that can accept 2 CIMs, and the default options seems to be about the gear ratio you want. Check if this will work with someone who knows more about your project though.

For a motor controller, you should probably get SPARKs (like one of the previous posts stated). They are the cheapest motor controllers you can get, and are even on sale right now .

just a question what is the purpose of a motor controller? and the gearbox will allow the independent movement of the two motors or would I need two of them?
