Lance already got to the HexBugs that were a featured toy for this company at Toy Fair this year. And we've written in the past about the VEX Robotics Design System, a robot-building platform for serious enthusiasts that sells for around $300.

Lying in the middle ground between cute, inexpensive toys and pricey, serious systems are the upcoming VEX RCR Mini kits. As with the higher-end VEX kits, you'll be able to follow plans to build specific little bots or create your own. The kit will be less than $100, though; it'll come wiht 300 parts, though additional accessories will be available; and most/all of the parts will work with the original VEX kit, in case you decide to upgrade. Look for the Mini kits in August.
