I don't know the P&S market but if I were looking for a low light model I'd limit my search to those with image stabilization. Good optical IS will get you two to four stops of improvement in hand holding which will in turn allow you to use lower ISO , all things being equal. P&S's in general range from tiny to those merging into dSLR like cameras and the larger and faster the lens the better. There is no silver bullet but do take IS into account in which ever model you look at. I do know that the Canon G9 is pretty much THE pocket camera used by serious photographers who need a good, small camera. It has been end-of-lifed from what I have heard so the G10 should be around the corner. I have thought long and hard about that one myself as I struggle to open a Pelican case on a raft to grab a dSLR going down a river....
