Ebay offers HEXBUG Black Widow | RC Robot Spider for $12.15 (reg. $30.16) free shipping.

Product Description:
The HEXBUG Black Widow is the new eight-legged robotic creature that is an electromechanical marvel. The Black Widow features a large motor for even faster crawling, 360-degree steering, a glowing LED eye, and two-channel user selectable infrared remote control. The IR remote has rechargable batteries and enables the user to operate multiple bugs independently or at the same time (each sold separately). As the largest member of the HEXBUG mechanical family, the complexity of its internal mechanisms and eight-legged crawling motion is simply fascinating to both operate and watch.•
