yeah good point . I have even seen them with grips included around that price.
D750 is a funny camera. Thom Hogan referred to it a "fixed D600/610" with some D810 bits in it.
One wonders of the D6xx line will exit gracefully to stage left.
I am surprised they limited the D750 to 1/4000 shutter given the shutter/mirror mechanism is reportedly the same as the D810.
