Cameta Camera offers the refurbished Nikon D3100 14.2-Megapixel Digital SLR Camera Body for $279.95 with free shipping. That's tied with our mention of a refurb from two weeks ago as the lowest total price we've seen for this camera body. (It's also $39 under the price of a new unit.) It features a 3" LCD, 3fps shooting, 1080p HD video capture, HDMI output, pop-up flash, SDXC card slot, and more.
A 1-year Cameta Camera warranty applies.
