In theory, no, not at all.
What does bother me though is that australian ebay is quite limited with the amount of amiga gear for sale, and slowly but surely there's one or 2 people buying up a lot of gear and then selling it for absolutely crazy prices ($700 cd32, $300 c64 emulator for amiga, $50 powerdrift, and many, many other examples). Not only does this make amiga gear unaccessible to me, but it just goes to waste and is posted week in week out. Probably half of what is available on australian ebay is this sort of stuff that does little more than take up space in the list of "amiga" items, and makes there be less available amiga gear for those of us who actually want amiga gear.
I have no problem at all with people being lucky enough to buy cheap stuff and selling for a reasonable profit, but the aforementioned people are making it hard for me to get ahold of amiga gear (Ive been trying to get myself a working amiga for quite some time and those people are making it very hard for me).
