I bought the entry level D700 and certainly have no regrets and never had any kind of problems. I noticed that Amazon found a new-in-box D700 and is asking $3,700 for it. In fact, for what I do, I don't see any need to buy either a D600 or a D800. I've got the big viewfinder, I've got 8 fps and Ive got some good glass. Maybe a D700 would fit your needs.
