Cameta has some manufacturer refurbished Nikon D5100 kits that they have
marked down to:
$539.95 (body only): http://www.cameta.com/Nikon-D5100-Digital-SLR-Camera-Body-Facto
$589.95 for the body and 18-55mm G VR DX AF-S Lens: http://www.cameta.com/Nikon-D5100-Digital-SLR-Camera-18-55mm-G-
Tax and shipping are free (if you choose UPS ground) and the reviews on
Reseller Ratings: http://www.resellerratings.com/store/CametaCamera
are high. Customer service seems to be very strong based on the reviews
and responses from Cameta to negative reviews.
There are a few accessory kit options available, but nothing in any of the
kits seemed to be worth the extra cost. I'd look on Amazon for any of the
accessories you might like/need.
Personally, I added the Nikon 35mm f/1.8 lens (at $200) to bring my total
package to $790 which is a little less than a brand new D5100 with kit lens
would have been.
