Well, you could pay $10 for it here if it would make you feel better.

I haven't tried that mouse myself, so I couldn't speak to it's quality. I'd guess that it's probably not as high quality as your mouseman. It's probably pretty lightweight, but considering the fact that's it's as barebones as one could get with a mouse, I think that the price is probably about right.

EDIT: I just checked Belkin's website and found this 3 button ps/2 mouse for $10. They also have a USB version.
