Hamjam, I agree that you need more or different options on the poll.
I would have chosen D800e as I already have the D800. Two main reasons I bought the D600 were price and availability. I think the D600 is a compromise between the D7000 and D800 with the D800 worth the extra money. I also think it would be better for what you want to shoot. There are now some used ones available at a reduced price. However, if you buy a new D600 or D800 this month, you can get a $150 instant rebate on a 28-300.
