I see what you mean, and I think your onto something there. A U.K. based Emovie-type site. Not being a dealer, I have never been bothered about selling... This does sound like something I would use, and often if it turns out anything like the U.S. based ones.
Personally bar the odd very rare item, I've stopped buying from the States, due to the amount of money the postal service was taking from me. So I buy almost exclusively from Europe. An auction site of that type over here would be most welcome.
If your thinking of giving it a go Paul, good luck, and count me in as a customer...
