We need a new camera too, so I've been researching this. Our main thing was to have a camera take super fast pictures (minimum "shutter lag"). The camera I want is $300 though...Canon PowerShot SD970. Supposed to be awesome! The faster the picture taking, the more expensive it gets. Although, the Kodak EasyShare Z915 is relatively quick and is less than $200.
