I've only bought two Amiga items on Ebay, those deals worked out all right. I would imagine that the seller rating is a very good guide as to the reliability of the seller, as well as the general quality of the auction page.
The only beef I currently have with Ebay is that I often lose items because someone outbids me on the last minute, but that's just my fault for not bidding high enough.
I think that it is the quality of the people, not the channel for dealing with them, that determines whether you will be happy with your trades. Amiga owners are generally a very reliable and accomodating lot, but unfortunately there are a few bad sectors on our otherwise healthy and validated disk :-D
