I have what's left of one
I found one in a skip when I was walking past last year. When I pulled him out from under the rubble, he was missing an arm, but I thought, what the hell.
They are a veritable goldmine of useful bits. Motors, springs, touch sensors, infra-red, microphone, speaker, LED's - all sorts.
I am currently fitting a servo and a small video camera inside his head, ready to mount on my Robonova-1.
They are so cheap on eBay now, my advice is get one. Even if you don't like him, you can always cannibalise him
