I kinda asked the same question and was pointed in the direction of a few cams. I wanted to upgrade to a smaller cam with half descent still capture capabilities. Seem to boil down to these...
Panasonic SD9 Small/light 10x zoom, takes SDHC memory cards, Pre Record function I like too.
Sony SR10 Maybe just too heavy/big, 15x zoom, 40Gb HDD, also takes fairly expensive Memory Stick Duo.
Sony HDR TG3 Pocket size cam, 10x zoom, expensive memory sticks again.
Canon HG10 10x zoom, 40Gb HDD, stills to MiniSD card.
Canon HF100 12x zoom, takes SDHC memory card.
Cheapest is the Panny and I am leaning towards that one anyway
