indeed, otherwise I'd be expecting people to sell their houses with no increase over what they paid for them in value, just to be fair to everyone.
I'm sure DQ would agree?
That said in the particular case that started this debate I have no idea what I paid back then so have priced at what looks to me reasonable v the cost of a new one. As always if anyone wants to make an offer of what they think its worth........
With stuff like this the other consideration is always what it would cost me should I require another one in the future and I doubt I'd get one for less than or even the asking if I find selling was a bad idea!
That said thinking like that is why I always have a cupboard full of unused gear clogging up the place!
