I've gone to websites such as Xoxide.com, who sell replacement teflon feet for seemingly any mouse. But for people who choose -not- to buy stuff online or are hella cheap and frugal... like me... well the method above is the perfect if not the only solution.
What you need is any old, non-working mouse that has some teflon feet to scrape off from, a glue gun with a glue stick, and of course the other -WORKING- mouse you intend to stick the feet onto.
I took the feet off of a dead Logitech MX-300 (optical) and installed it onto the optical mouse for my Power Mac 6100.
Here's some pics:
