Adorama offers the Nikon D90 12.3-Megapixel Digital SLR Camera Body, model no. 25446, for $599 with free shipping. That's tied with our mention from last month and the lowest total price we've seen for this DSLR with a Nikon warranty. (For further comparison, it's the lowest total price we could find by $81, outside of the price below.) Features include a 3" LCD, 720p HD video recording, in-camera image editing, GPS geo-tagging (with optional adapter), USB 2.0 connectivity, HDMI, and more.

A close price, Negri Electronics has it for $604.50 with free shipping.
