I upgraded from the D70 and haven't picked the 70 since. The D300 is brilliant in every way. I used some of Rockwell's advise even though some think he is sketchy. My son who is a good shooter seems to prefer the 300 as well. As far as the D200 is concerned, I shot with one a few times and it is a great camera as well. I was looking at the 200 but, I kept hearing rumors about the 300 and I'm glad I did. Like Kyle said the image quality at high ISOs outstanding.
