It is very risky buying from anyone on the net, ebay or not. I used to enjoy some real good deals, with some real descent people buying classic Amiga stuff. Amiga users seemed to be quite honest as a whole, and the first time I was ripped off was the first time I purchased a non-Amiga product from an ebay auction for an Intel CPU.
The myth was shattered by the last couple of ebay Amiga purchases I made (nothing arrived, buyer drops off planet, etc). Amigans are having their reputations tarnished along with everyone else.
It is sad a way, but that's my own risk I took, and am not bitter about it. I think I might only consider established online stores in future. Or possibly veteran amiga.org members that have been around a while, and not recieved threads like this...
