This is a tough question. In short it depends on whether you are a buyer or a seller.
As a seller I price my component high- hoping for the "Greater Fool" In short people with money here not the greater fool.
As a buyer I think an honest meeting in the middle between my motive (for free) and the sellers motive (a profit) makes for a good deal.
What really bothers me is when I'm a legitimate buyer with cash and want a legitimate used item price the seller pretends his item is worth what he paid for it,
In the end there are 3 things that force a seller to accept reality: Death, divorce and Debt. That's when the prices get real. To you old bastages who hope someone is dumber then you I say "good luck dinosaur"
