As a long time Audiogon user (always a buyer, not a seller), I am very cautious about buying online. It's just me but I would never, ever buy from an international seller. I have never been scammed but I empathize with those that have been. I just think that the cost of shipping a 100 pound amplifier half way around the world must outweigh any discount someone could give you. Also, if you mail a check then you have their address. I believe it would be worth the cost of a plane ticket to fly to their home and ask them face-to-face, "Where's my money?"
