If you are just wanting a casual camera but better than a point-n-shoot I would go with a Sony or Olympus simply because the Image Stabilization is built into the camera not the lense making the lenses cheaper to build.
That being said for low light shooting you would actually be better off with the Nikon or Canon because the lenses with Image Stabilization are more effective than the ones built into the body and that helps a fair bit in low light shooting.
Either way you really can't go wrong. Unless you are a proshooter (or at least an advanced amateur) they will all do the trick. More important is how they feel in your hand and how the controls are laid out and that is pretty much a preference thing and also depends on how big your mitts are.
Good luck! :thumbsup:
