Nikon is starting down the path of making pro level G lenses. I think that you would most likely want to look at the F5 or F100 in order to be able to take advantage of that trend. It's not a trend that I am happy with, but it is there so being able to use your current lenses and future pro offerings from Nikon to their fullest would seem like a good idea. BTW, KEH, an AUG sponsor, has F5 bodies starting at about $550 in bargain condition. Only about $100 more than an F100 in Bargain.
