Here’s a little story for you on that, not to get too off topic but it’s definitely illustrative of that thing we call “value.”
I bought a Kodak carousel slide projector brand spanking new (even in the original storage AND shipping box) through an online auction for $8. I put it on eBay for a month with nary a nibble. Finally consigned it to a local auction house for their weekly auctions and they had it for a month with no takers (and they start bids at only $5!).
They gave it back to me and I sat on it for a month or so before resisting it.
This time, it sold for $120.
