Best price on Nikon D3100?

I'm looking into purchasing a D3100, but it looks like buying new is going to be too expensive for me. So I was hoping that I could find a rerfurbished or a reliable used one in the $400 range if possible. Where is the best place for me to find that camera at that price? It would be awesome if you could provide links in your answer where you've found one at that price, because I've found them only in the $500 range.

The best I could do was to find the Nikon D3000 in your price range.

I suggest that you save up some more and get the D3100.
