I'm in the UK so I might try out the Jessops protectors but I have to say I'm going to see if I can get an 'invisible shield' protector. My iPod nano got one as soon as it was taken out of the box a few months ago, and it has been absolutely fantastic. It's true when they say you can key it and it's fine. wipe-clean etc. It's worked fantastically.
