Normally, I'm not a fan of posting ebay things. I will make an exception because I feel this is sweet. An ebay store posted half-a-dozen Sansa Fuzes for 20-30 bucks each. Many of them are scratched and such, but if you are thinking of picking up a fuze, it'll be hard to find cheaper than these.
There is also the SanDisk Sansa Fuze+ 8GB for $30 on sale.
