Via The Screen Savers: RobotStore.com sells a variety of robot kits, including the WAO-G PC-programmable "fuzzy" robot. I might very well enjoy a soldering-required robot kit, but I'm disappointed that the all-to-pieces model is just as expensive as the pre-assembled model.

Seeing this robot made me miss the days where I pined (pining for pining?) for a Heathkit HERO robot kit, a (relatively) popular programmable robot from a couple of decades ago, too expensive to actually be attainable. This site claims to have acquired the remaining kits and the rights to sell them, including the HERO 2000 and various modern add-ons, but there doesn't seem to be any resale information up yet.
