So today I picked up a spare Classic just in case using some vouchers (my current 6g 160GB has potential HDD issues) but I'm wondering whether to keep it or return it (I have 20 days). My Classic is insured against breaking but I'm concerned that they may only give me cash towards something as opposed to a replacement which obviously may not be possible in the future to replace myself. Right now I'm wondering whether to: 1) Keep the spare Classic. 2) Get a 5/5.5G off ebay and replace the battery/HDD. 3) Something else, but I haven't found anything unless I've missed something. I'm just wondering what opinions others may have.
