Don't do it!
Dude, you got one of the first 100,000 or so iPods ever sold. Jobs just showed us the 10 millionth! I am in the same boat as you, but I decided to just RETIRE the old banged up beauty while it still works and get a Shuffle since that is exactly how I use my iPod anyway, and don't mind refilling it every so often. I would just save up the money, you never know how these may be coveted in the far future.
