If you can't decide between a D300 and a D3, why not just buy a D300 AND a D700. I have uses for both. It shouldn't cost that much different between both D300 + D700 cameras and a D3. One huge benefit you would have in buying the D300 + D700 is that you have a back up camera in case one stops working.

Went with the D300 after trying them both out. I actually like that it is MUCH lighter than the D3. Plus, with the money saved from the difference from the D3 (plus our shop had a $300 discount on the D300), I'm also going to purchase the Nikon 70-200 f/2.8 vr lens and the Sigma 150-500 os f/5-6.3. And eventually the 50 f/1.4 or the 85 f/1.8. I think I should be really happy with this camera!! Hopefully I can take some good enough pictures to post on here and have you guys and gals look at them...

if you get into landscape work also look at the Nikon 16-85 VR to cover your wider range. It's pretty good glass for the price.
