I was searching the web last night, and saw a nice deal. A D300 with Battery grip and memory cards, (15,000 photos) for a about half price from original purchase cost. I recently bought myself a Nikon 200-400 f4 VR and am loving it by the way. But I want to get a-bit more speed out of my camera. My subject matter, generally includes landscapes, sports (rowing, rugby, hockey and today snow boarding), wildlife, macro and portraits. I've been reading a few reviews, and they say that the D300 is a good camera but that the D700 is far superior even for the large cost. I could sell my D5000 (6,000 or so frames) and get the D300. Anyone think that this is a bad deal? I don't like parting with my equipment, especially when its so new. Or would something like a D90 be better? Or shall I just contuine saving for a D700? Thanks for the input.
