Just out of curiosity, are there similar deals around for the D800? I don't shoot Nikon so I don't follow them but I an curious if these sorts of deals on Nikon gear pop up every now and again.
I've seen Newegg selling the D800 for around $2100, so yes, there are deals.
The problem with a D800 is the lenses. Only a few match the high MP sensor, and they have horrible CA, so you have to work on them a lot.
I use live view, and that really did not work well on my D800, so if you are a liveview user, think twice.
At ISO 200 in high contrast outdoor lighting, it can be truly amazing. For low light ISO 12800 indoor shots, its amazing as well, but not in a good way.
