Surface Pro bags/etc... and skins/screen protectors

Hi,I'd like to get a list of favourite bags or slips for your surface pro or RT....also, I've already found a scratch on the back of my surface pro...thus I'm interested in a full body skin but the only ones I've seen are really expensive...don't want a styled one, just a clear one.Thanks in advance...PS-Pics or links for both would be great
