I have taken several CDs (mainly my Dad's, not my own) from unusably scratched to relatively pristine. The really bad cases need fine grit sandpaper (wet!) followed by plastic polishes. I generally start with Meguiar's plastic polish and work my way to Radtech Ice Creme. In my own collection I have CDs that are around 30 years old and are error-free. I'm not interested in formats or services that won't last at least as long or can't be backed up to my own NAS (nor am I interested in anything less than Red Book quality).
