How much do you think a used samsung u600 would cost if i were to sell it?

Hello, well I have a a shiny thin purple samsung u600 and its amazing. Its on orange which i also love. However I'v had it for quite a long time now i got it newly when it first came out and i was wondering if i were to sell it how much do you think it would be for? It doesn't have any scratches apart from the colour slightly coming off on one of the buttons but you can hardly tell.How much do you think a used samsung u600 would cost if i were to sell it?Check out CycledCells.com.
