I believe EBay is probably a very good indicator of the rarity of Amiga items. No one is trying to say EBay is the only place equipment is available or that there isn't a lot of items thrown in the dumpster. But I can pretty much assure you that there are more A500's thrown in the dumpster than PIV's. Why? Because there are a lot more A500's floating around. I will say that price alone on EBay is not the only indicator of rarity. You also have to factor in desirability.
