What Rockwell found is that at high ISOs, the D300 is a tiny bit cleaner, but it applies more post processing to smooth out the noise. That processing fuzzes the image up a bit. I'd prefer to do that in Photoshop myself and control the degree of the tradeoff. I like Rockwell's site because I can see exactly what he's doing and where he's coming from. He doesn't do in depth scientific tests, but he has a lot of common sense and knows how to apply the technical stuff to the way things work every day. That's rare in this internet full of people citing specs without understanding what they mean.
The D300 just started shipping. There's a delay between the orders and the deliveries on Nikon stuff. When that lag gets pulled up, you'll see the D200 come down in price I bet. If you can wait a couple of months, the D200 will be a lot cheaper than it is right now.
See ya
