I bought a 30GB 3G iPod today from my place of business for $100 today. Obviously it was used, and obviously it's scratched to hell. (Not heavily, just the sort of "typical usage" scratches.) So, then, what's the best inexpensive solution for these scratches? To be honest, I could live with the scratches on the back and the ones on the actual white parts. (Except maybe one on the wheel...) For the most part, I'm just interested in getting some of the scratches off the screen area. Ideas?
