Hi. Robot-Crazy. I don't know that much about finding robot kits and finding ones that are reasonably priced. You could (if you have not already) try searching google for robot kits. The one I am getting is a bit pricier than what you were hoping for. :( I will send the url and see what you think of it! http://www.yostengineering.com/index.cgi? section=Hardware&subsection=BugBrain/BugBrain.html
Renee :) Welcome to the group! Happy you found us-though as you know of course I am as new as you!
