Just a quick note that we've noticed you can grab a refurbished Nikon D600 for a little over $400 off the new price at B&H. This is Nikon factory refurbished to original like-new specs, and likely were used as a quick loaner or as a review copy. That said, I'm willing to bet they're in great shape. Get one for $1584, which is a slick deal for a full frame sensor.
