The SD1100 with an external battery adapter. Battery life is pretty good when you throw a few thousand mAh at it.
The adapter can be had out of China for 1/3 the going rate from Canon.
The Kodak Zi8. 1080p/30 or 720p/60. Pretty darned decent low-light. Can take a 32GB card just fine and has a 5v barrel plug adapter handily included right there on the side. Even includes a USB power adapter. If you watch the Fleabays they can be had refurb'd very inexpensively.
