Kinetic Creatures, Lego and Scratch

I was browsing Gizmodo on my Xoom and came across Kinetic Creatures and their creations -  a rhino, an elephant and a giraffe. They looked really good and I wanted at least one but am too tight to pay the asking price.

When I also saw that they could be powered by Lego motors and, therefore, programmed using Scratch, I was even more tempted to buy one.
Decisions, decisions.
