DxOMark is the trusted industry standard for camera and lens independent image quality measurements and ratings - DxO Labs is also behind the software DxO Optics Pro, a "Photo Enhancing Software for Mac and Windows", which is said to have the best RAW converters out there, compared to Adobe Lightroom and Apple Aperture. Long story short, the latest Nikon Cameras are the top-leaders of the DxOMark scoreboard - with the Nikon D800E scoring 96 points and the Nikon D800 scoring 95 points.
The Nikon D800E as well as the Nikon D800 are in stock on amazon marketplace, so make sure to get either model. As previously reported on nanofunk - the differences of the D800 to the D800E are minor - but both models are highly recommendable cameras. I just ordered myself a D800E, expect some in-depth experience postings here soon.
