How much should I sell my Nikon D3100 for? - 1

I got the camera back around christmas time of 2010, and i didn't really use it that much, there are absolutely NO scratches or dents or anything on the camera, it looks brand new, the lens is in perfect condition and all the buttons work like new, its BASICALLY NEW, and I want to know how much it would be worth. Because its still considered "used" maybe simplified into "like new" but I need an estimate on how much i should sell it for.

Do some research on ebay, Amazon and your local Craigslist, then you'll know how much the market can handle.

The cheapest used (also like new condition) Nikon D3100 on Amazon is about $520, you can sell it around this price.
