ahahah this thread is amazing, first off he asked for price range of up to 350, yet you are saying pick up a d200? what the fuck are you on, even a d50 just body wont be in his price range, get a grip.
You arnt going to find a camera that does good video and good stills, you can find a still camera that does a semi ok video, or a video camera with semi ok stills, but you wont find anything that does very well at both.
personally id say for what you want, just try and find a simple point and shoot, something like a lumix would do you fine.
If you want to get into real photography you really need to up the price range a bit, and downplay the pocketablity of the camera, so over all id say your best bet would be with a simple point and shoot, just make sure it has a high mega-pixel value and good optical zoom is always a good thing if you plan on being a bit away from shots.
