Having a look on the apple site you can get the same ipod for £299 with free shiping the one on ebay is already £204 with shipping and still has 12hrs to go.
Yes the seller has got good feedback but they have also recived 12negs in the last month. If theres anything wrong with it you'll have to pay to ship it back to the states and the manufacturers warrenty is state side as well.
Personally if it was me I'd buy one from the apple site by the time the biddings ended you probably won't get much of a saving from the uk price.
