I've got 2 IPOD Mini's The catch is I don't have the charging cables that I can get rid of. You can get them dirt cheap on ebay. since my iphone uses the old cable I'm hanging onto the one I had.    
I will charge them up to show they work.     
6gig 30$ Silver 
4gig 20$ Blue   
I replaced the batterys in both of them a few years ago and as far as I know they work great my wife used hers in the car all the time. We just don't need them any more with our iphones.   
Buy them both for 40$ and I will toss in 1 charge/ipod cable
