This may be somewhat beyond your sense of "reasonable", but in Orlando, on the southeast corner of where Route 4 crosses over Fairbanks Ave,. is a surplus place called Skycraft. They sell all kinds of strange stuff, lost of electronics, and lots and lots of stuff that would work well on a robot. And generally inexpensive.

As a geek, there is no better place in all Florida to visit.
