D300 or D300s?

Are you buying/comparing these new, or used? If the D300 is used and the D300s is new with warranty, the price difference is reasonable. If you want video capability, the choice is obvious. Otherwise, there is almost little difference between them for still images. I use a D300, and the sensor cleaner must be pretty good since I've never had to remove any dust manually from my camera's sensor, and I've shot in mud, dust, rainy conditions. Also, the CF card door is better designed (in my opinion) which was changed on the D300s. I don't think anything on your list would justify to me the price difference unless video was important. That's really the difference between them, but the video is limited to 720p HD @ 24fps max. which is quite good, but in a spec war looks behind the times.
