It is all relative. I am not a pro, but sticking to those specs, I limited my expenses by not jumping on every interim hardware

They probably smile more when they sell more than two DX bodies plus a Coolpix
Again, I only bought one Coolpix and two D200 in 12 years, the second one used, less than a year ago. Granted, I also have 18-70 (came with the first D200), 70-300 (I wanted "reach"), 35/1.8 (very low-light abilities), 17-55 and 70-200 (the last two for concerts and shows indoors).
So I saved enough that I can afford to get the D400 even if it costs twice the price of one D7100.
