Any DV camera will probably give you crappy stills. I have a Canon Elura 40MC and it's nice for video, but sucks for still photos. I believe there is one company that has a swiveling lens that has video on one side and a 4 megapixel still CCD on the other. The reviews noted that the camera didn't do either well. Most DV cameras will only give you 1 megapixel resolution anyway.
