During volunteer time as a lab assistant, they let me use a great Sony DV camera that doubled as a high-res digital still camera. It had PCMIA adapter that linked it to a storage type for the still images (either floppy or sony memory stick) and a mini-dv tape socket for the video. I'm not sure of the model number but I think it was around 25 grand. The image resolution was 2400x1200 max and it was pretty great image quality (enough to correctly display 300 micron brain slices with tumors in them), better than any mid-range digital camera I know of. Not to mention the lense was absolutely fabulous, a Carl Zeiss I believe, I was able to focus on stuff less than a cm away from the tip of the lense with unbelievable accuracy. I'm not sure about all the functions (if you're planning on using it in professional grade photography that is), I didn't get a chance to mess around with the aperture, exposure or focus range settings, but I'm sure it's equivalent to your average $1000 digital camera.
Not sure if that's what you're looking for or not, but hey that's about what you'd expect if you're looking for great still coupled with DV camcorder. I'd be much cheaper and prolly would make more sense for you just to get a mid-range DV camera and a still camera separately. Kodak's new DXsomething model with the dockable port is very cheap (a little over $180 listed on cnet) and it's a great camera. Couple that with a mid-range DV camera and you've got your memories right there.
