Hey,
Having a clear out recently and found an old iPod of mine, it's a 20gb U2 iPod, with the signatures in the back. Not really sure of it's worth cos I haven't come across one for a while, but found one for sale on a UK forum for £60, comes with the accessories too and is also boxed still.
Here's a few pictures to show what you'd be getting.
Think £50 ONO including delivery is a fair price, if anyone feels otherwise feel free to say!
Cheers,
Ben
