I wanted to add some thoughts regarding this eternal fear of grey imports and the so called Nikon warranty. This is only ok as long as you can get a replacement body. As far as repairs are concerned, you wouldn't want a tech monkey messing inside a camera that is precision manufactured by delicate machinery under certain conditions, I would throw away the camera before letting that happen.
I bought mine here in the UK from SLR Hut who I believe are a US company, the price was great and the order arrived within a few days all brand new and working perfectly.
The first and last camera I sent back to Nikon UK for repair came back with the horizon 1 to 2 degrees off level and took me forever to to fathom as I thought I was always shooting crooked and only rigorous testing reveled the real problem. The geniuses at Nikon must have installed the sensor back wrongly when they put the camera back together.
