Last trip I was disappointed with the way some of my night shots turned out. I am looking to possibly buy a new camera before our trip this october. I am looking at the sony dscw80. The ISO is around 3200, it has image stabilizer, and 7 megapixels. I didn't know if anyone has this camera or might have some opinions as to what else I might need to consider. I know I don't want to have to take 5 or 6 shots before I settle with the less blurry of them all.
