I don't think you will find a big zoom point and shoot that you will find satisfactory in low light.
But ... here is a recent comparison review of small big zoom cameras:
I'm currently looking to by a new camera to replace the horrible one I have right now. I am a total amateur and don't know that much about cameras, though I am doing a lot of research to avoid buying another piece of junk (Olympus FE-46). I take a lot of pictures at shows/concerts so it's very important for me to have a camera that does well in low light, and that can shoot HD quality video.
So far, the best suggestions I've gotten are the Canon PowerShot SX200 IS, Fujifilm FinePix F80EXR, and Nikon Coolpix S6000. I was just curious if anyone had any opinions on which is the best of the three or any other suggestions before I make a final decision here.
