Rating system insanity

I purchased a PS Audio P10 from a dealer who claimed he used it at one show and therefore rated it a 10. The unit is black, and he did post a couple of bad/fuzzy pictures. When the unit arrived it was clear that he had set something heavy on top of the unit that left 3 wide scratches/bands across the top of the unit, not to mention the unit was really dirty. When I called him to discuss the condition of the unit he told me he was not responsible for dusting and or wiping down the unit before he shipped it and denied there was anything wrong with the cosmetics of the unit. I asked how he would know since it was covered in dust? His reply---oh your mad cause I didn't wipe down the unit. The good news is that PS Audio sent me a new top which I can install. Guess this is more of a rant, but very disappointing that a dealer would take advantage and then NOT be willing to help in any way. What happened to taking some pride in the way you conduct a sale. I know that when I sell something I take a very close look at the unit to make sure it is graded correctly. I want the buyer to be thrilled when they recieve the item they paid for. I have owned a number of PS Audio products in the past and they will continue to get my business.
