I have the cg65 which is the same as the CA65 but not waterproof, in low light its not great but passable. I have posted a clip (end of a cat fight so don't watch if your an animal lover) on
http://www.vimeo.com/925839 if you want to see the quality, it's best to download the original clip so you can see it without re-compression vimeo adds. The downside of this camera is that the battery lasts 50-60mins, only 5x zoom, and 30fps where 25fps is used for tv in this country. The good thing is the size of the camera which easily fits in a trouser pocket, and it does take a reasonable photo to boot as well, also a 4gb sdcard will hold over 2 1/2 hours worth of video at highest setting. I sure you could get a reasonable mini dv for the top end of your price range if you want better picture quality.
