If you have a Canon PowerShot, and it's supported by CHDK, it's worth a try. Though the user interface for the CHDK side is terrible, it adds handy features like intervalometry, cable remote, extremely fast flash sync, and a huge set of image and video options.
Yeah, CHDK has some nice features, but it's clunky to use. To some extent, that's because the GUI has to take place on the camera display, which is very, very crowded - and accessed by the limited number of camera buttons and knobs. The gphoto2 project is apparently working on routines that would allow a CHDK equipped Canon Point-and-Shoot to be controlled from a remote computer. Then you could run a very nice user interface on the computer. I'm using gphoto2 for camera control of a Canon T3i, using the Tcl language for the GUI. I have everything working, including liveview, although there is a bug in gphoto2 which affects this camera. (They're working on it...) Is anyone else on this list using gphoto2?
