I recently got a brand new 30gb Video iPod using the student rebate. My friend wants to buy my old iPod and the accessories i had for it. I want to give him a fair price. What would be a fair price for the following all together: 20gb 4g iPod with firewire+usb cables, AC Adapter, iTrip and a silicon cover. I've already looked on ebay, but i can't seem to get a good grasp of what these things are going for. Thanks in advance for any information.
