I signed up over at Vimeo.com, it is a site dedicated to user submitted videos. You can search for videos shot by camera model. I narrowed down my list of possible cameras by features and price, then I went to Vimeo and downloaded a bunch of videos from those cameras to compare to each other. You can download raw video files from the cameras, instead of looking at a compressed youtube videos. The users do all kinds of low-light tests, and upload the results. It really helped me decide on my Sony HDR-CX350v. Check it out.
