Looking for a Keyboarding program AND curriculum

Hi - we are a K-6 school looking for a self-paced keyboarding curriculum for our 1-6th graders. Our 3rd-6th graders would need to have their own accounts to keep track of their wpm progress by taking typing tests. Grades 1 and 2 need to learn home row finger placement and key identification.

We are considering learning.com's keyboarding program (EasyTech) and a program called TypeRacer, among others. Your thoughts are MOST appreciated, and the most cost effective solutions are best (that is a no brainer!).
