Think that should be worth about $250-300 for a set that is in good condition. You can see B&S for a feel of the price. If someone is selling at a certain price for so long and no one seems to be keen, likelihood is that the price is too high already.
Anyway, all these are a matter of perception and is purely a matter of demand and supply, obeying the basics of economics. If someone is willing to pay $1000 for it, then the price will be $1000 ;p
However, for the seller, sometimes they use gimmicks to promote their wares such as testimonies / pics that they taken with the camera to proof that the condition is good and the colours are sharp ...
