Just depends what people are willing to pay, alot of sellers look at other razor orices on E-bay and set thier own Auctions accordingly,.....alot of us on here generally know the going rate for a type of Razor, and we know what we will and will not pay.
i remember when you could see Eclipse Red Rings up for £30.00, didn't want one then, then someone on a forum get's one. people start chatting on the forums, and demand goes up then so do the prices, now the price for these is stupid, would love one now.........
Fatboys used to be really silly money, now they seem to be coming down.....
In a different way look at the Feather All Stainless, i think it's overpriced at £130.00 but i really wanted one etc etc, If you really want a razor and you have the wedge to buy it, good luck to you.
