PC Magazine has a review of the RadioShack VEX Robotics system. The VEX system was built with the education market in mind and is part of Dean Kamen’s popular FIRST Robotics competitions. At $299.99 (not counting batteries), the VEX System is more than just a kiddy construction set. It is best suited for the scientifically inclined teen (or classroom), and is a perfect fit for the robo-hobbyist who can’t afford an AIBO, but might be willing to build his own metal companion. Link.
