HP35 Price on ebay - what am I missing?

[aurelio]

About 15 years ago I bought on TAS (ebay) actually not a calculator, but a collectable item quite rare. The first time I saw it for sale from a german seller I lost the auction at the last minute 'cause of a connection problem, the winner was the only bidder . I was so disappointed for that... suffering for weeks After a few months I found another one maybe in better conditions but with the buy now option and I bought it for quite two times more the price of the first bid.
Now with cold mind never I should do the same thing, never, but that time I did it, maybe just for the pleasure to own it, I think its real value is nowadays a fourth of the money I payed...
Just to say that often the value of a thing is just a personal matter.
It could happen that we give to a calculator a value higher of the real one, but maybe just for a sentimental reason. isn't it?
