Thank you very much for the reply. I have, indeed used the CHDK before. At this point I only purchase Canon cameras just so I have access to the CHDK. I just wasn't able to find the kit for my camera on the wiki downloads page (
http://chdk.wikia.com/wiki/Downloads) under either the stable or beta downloads.
I thank you profusely for linking me to the download on the other site. Now I can FINALLY override the shutter speed limits and (hopefully, though I haven't looked at the capabilities of the kit) get some bracketing going on for HDR shots.
