OK, Chip - in that case, I go with the robotis. I beleive this has benefits to both astronomy and other Earth applications. Controlling a self-regulating robot (or however it works) across the solar system is pretty impressive!

I like G-K's idea of a new theory of physics, but there is no guarentee this will be discovered any time soon. Sorry.
