Try and find someone willing to sell a Mint Minus copy of the Illusions "City Of People" nowadays.
Ha, believe me, I have!
I do see where you're coming from but think you're talking as a guy with vast, valuable experience. Most sellers on Ebay have a mere fraction of your knowledge. I see ebay as essentially a giant flea market and my expectations of sellers is low. I don't think this seller is particularly unusual in their listing, indeed I think they're trying hard to be as honest as possible. You are right, there is a wider problem though and I even accept I'm part of the problem (I'd still take that beat up copy of The Illusions that was much maligned on here recently, i just don't see me finding any other copy any time soon, though you never know).
I sold a very desirable funk record last week. It's a record I have owned for a long time, 10+ years. It was a genuine G+ record in my opinion, and I listed a visual grade and a play grade, both of which I thought were honest. I listed it on various funk groups at a very reasonable price but no one would touch it. Why? Because to them a G+ record is borderline unplayable. Even a VG- is often unlistenable in those circles, in my experience.
When I did find a buyer, he was absolutely delighted posting feedback along the lines of "Amazing record, way above grade". I can assure him, it was very accurately graded, he's just used to really shitty sellers who are unscrupulous.
As I said in my initial post, I'm trying to cut out ebay these days because it is so unreliable, I've bought numerous records from BW and, indeed thanks to yourself, Bill Nadolny recently and its a joy. Their knowledge is vast and their reputations speak for themselves. If I could buy all my records from such sellers, I would.
There is another item on Ebay at the moment that I covet and I'm considering my bid, but the description is vague and although the seller has lots of positive feedback, I just dont trust ebay anymore. A soundfile, at least, would help.
In short, I agree with your wider points, but think there are many worse offenders than the guy identified above who is at least trying to mitigate for their lack of knowledge.
