I've been looking at purchasing a second body. Currently have a D7000 with the standard kit lens, and some nice FX glass (24-70 f2.8 and 70-200 f4). I was going to bite the bullet and get the D800, but had to take a look, at what i do with the camera. Shooting for me has been more of a hobby, but considering some weddings and shooting at our church. Love doing landscape and portrait.
I've always enjoyed having the best but also look at the reality also. One of those if you get the 800, and regret spending the extra $1000 and really need it or, or buying the 600 and regretting that one, and should have got the 800.
