Where can I buy a 10mm gear/rotary wheel?

Question

I was trying to fix an old disco ball. The problem was that it was turning on a gear. The teeth of the gear where worn down. Now to fix it I need to purchase a 10mm gear with a 4mm hole. I prefer a website.

Go to this link, in the upper left, type in 'gears'.
