The camera you describe has not been built yet.
There are only about three small cameras that have above average performance in low light.
And none of them are "tough" cameras.
A word about fireworks:
Most small cameras have a fireworks mode.
In that mode, the shutter will stay open for several seconds so that you can collect the full effect of the fireworks.
That means that you need a tripod to support the camera, because no one can hand hold a camera for several seconds without some camera movement, which means blurred images.
I got sand in my camera (canon powershot sd1100 is)and it busted! I liked the camera but had trouble with blury photos. I use it mostly for events/holidays, pictures of my kids and vacations but my kids are always moving and need something that will help me get a decent photo. My budget is $200-$400. I am VERY rough on equipment and often drop things so it needs to be tough and waterproof wouldnt hurt but not willing to sacrifice clearity for it. Another thing I didnt like about the sd1100 is the low light/night photos. For example, fireworks were just a big blur! We are going to the lake this weekend so I need to get something quick so any advise would be appreciated! thanks so much !
