I've used Ebay a LOT and I have to say that I've had very little trouble. But, one the one occasion that I was scammed on an expensive item (only £50 but hey...), I put a claim into paypal saying that I had not received the item and they actually reversed the transaction immediately. The money came back to me until finally the dispute was found in my favour and the case was closed.
I think this reversal of funds only happens when you deal with inexperienced sellers though. If they've been selling successfully for a long time I have a feeling that they become "trusted" and in that case you don't get your money back straight away but, if the dispute is found to be in your favour, you get your money back then. If the seller can't prove that he sent you the item then you'll get your money back I reckon.
With regard to having a blacklist on here... yeah it *is* a nice idea but I'm not sure it would come to fruition in the real world. The main problem would be deciding who goes on the blacklist. That sort of thing would have to be left up to amiga.org moderators, but then you're asking them to get involved in ebay rows and take sides on it. The issue becomes even more shaky if the row involves two amiga.org members.
So, unfortunately, I don't think a blacklist would ever make it on to here, as nice an idea as it is.
Hope you get your money back,
