Hi Mark
When I visited New York last year there was a huge photography store that seemed to sell stuff at reasonable prices. (

I have no experience of Nikon equipment, having always preferred the lightness and smaller size of Olympus gear, but I know some people on my photography course were Nikon users and they seemed happy with their equipment. Have you gone into a store and tried the combo you want, to see if it fits you hands and feels comfortable to hold, (there should still be plenty of stores within a short drive of you that sell that sort of gear to try)
I am a member of a very friendly Olympus forum and they offer advice and guidance (and equimpent rental) for people like me, they also allow members to sell their equipment to other members... I can only assume theres one for Nikon. It might be worth looking into a Nikon forum to see if they have a buy/sell area.
Good luck with this, and I'd like to hear how you get on
