Two years ago I paid $80 (US) for a pair of S45-2s without stands. A month ago I was outbid on a pair of S45-2s with stands; if I recall correctly my high bid was $140 (don't recall the high bid). Last week a pair sold with stands for less than $80 and the reserve wasn't met. But the stands and the speakers had been modded. Another pair without stands sold for more, but no mods.
The biggest issue here in the US seems to be a bunch of sellers that are either (a) selling junk knowingly, or (b) selling wonderful speakers unknowingly. It seems most of the passive B&O speakers selling in the US on Ebay come with this caveat:
"They seem fine but I have no way of testing them because of those funny plugs B&O has."
