How much would a broken ipod sell for?

It's a 4GB older ipod nano (like this one http://bindapple.com/wp-content/uploads/2009/11/ap... ), it works perfectly, but the screen got damaged and is completely white. I've tried resetting it, i've tried turning it on and off numerous times, i've tried letting the batteries run out and recharging it, but nothing works. you can still listen to music on it still, and everything, but it's annoying as hell to try to figure it out without having a screen to look at. so how much would it sell for on ebay (i'm thinking for parts), and would it even be worth selling? thanks guys.
