You can make your own quite cheaply - with LEGO Mindstorms. I bought a set for my dad last christmas and he's been playing with inverse pendulum ever since. :)

How long did it take your dad to build it? What type of expertise is needed?

The vid I linked to is not my dad's. I think he got a segway-style 2 wheel robot to work. Took him about two months, but he doesn't have much spare time. The biggest problem was adjusting for inaccuracies in the measuring equipment.
