The problem is that you cannot find any new D7K around.
Since many months ago there's not a single unit of a brand new D7000 in any major stores.

I bought my first digital SLR (have had a film one in the past) a bit more than a year ago.
Went for a D5100 in loco at B&H.
At that time they had D7000s in stock.
I now regret not have taken the plunge to a D7000, in general a better camera than the D5100.
The image quality is practically the same of course, but there are many more features in the D7000.

But now I will go to the brand new D800 or wait the release of a new DX such as the replacement for the D300 if this will exist sometime.

I just hope I can find them in stores when the time to buy a new body comes.
