Smaller Cheaper Robots

[sanddrag]

Lately (more like today) I've been interested in smaller cheaper robots. I've been looking at things like antweight battlebots and also the hobbyweight 12lb class. I've also been looking at super tiny pager motors and stuff like that. There is Vex but I'm looking for something a little more custom, not like a kit.

With how expensive robots are, as size goes down, price does too (although probably not by as much as it should)

So I have a few questions. Has anyone built any small or cheap robots? If so, let's se them.

Also, I was wondering if anyone has been involved in smaller fighting robot competitions? If so, how is/was it and how do you get involved in them?
