I agree with Zaikesman.
Only new should really be a 10/10.
9/10 should be reserved for almost new, rarely played equipment. (Either not even, or maybe just, broken in).
8/10 should be for used, but well taken care of equipment (like most of us have!).
7/10 should be for equipment that has started taking small amounts of abuse (i.e. scratches, dents, things that don't really affect the actual playing).
6/10 should be for equipment that is really starting to take a beating, but still works as intended.
5/10 and below should be reserved for equipment that is either severely visually damaged, no longer working as new, broken and no longer working, and/or a combination of the above factors.
This system would really let the purchaser have a better idea of what to expect when buying equipment. (Of course, you can always ask these questions of the seller! I always do.)
My thoughts on the subject anyway!
