I picked up a used D200 from a wedding photographer who had already upgraded to the D300. The D200 was his backup. It's an awesome camera. I used it over the holidays to take some awesome pictures--sometime by luck as I didn't modify enough of the settings when taking different shots. I'd even say a lot of the pictures were by luck.
Last weekend, a friend came to visit with her baby. I grabbed the camera and no matter what I did, I couldn't take a decent picture--with flash, without, changed metering, changed mode. Nada.
I didn't know that you can actually save different settings to different Banks (A,B,C,D). When I read Ken Rockwell's review and user's guide, he didn't mention anything about the different banks for different settings
