http://www.dpreview.comOne of the very best review sites for all Digital cameras. From SLR to $100 models. Very in depth.
When looking at digital cameras, the two things I have to stress the most are make sure it had a good optical (not digital) zoom. Digital zoom really lowers the quality of the photo. Some cameras just have digital zoom which I would avoid like the plague, most have both. If you need me to explain the difference more... I can.
Second, save yourself the grief and buy a camera that uses AA or AAA size batteries. When I was in college I worked at Batteries Plus and camera manufacturers are horrible. They will design rechargeable Li-ion battery packs that are specific to only a few models. So when you're in a bind needing a battery right then and your batteries are dead, you up a creek. You'll generally have to buy the batteries online. Manufacturers are getting worse, most will not set on a standardized battery shape/size. Our store carried about 30 of the most common sizes for digital cameras (Li-Ion packs that is) and its not funny how many times we'd have people come in for a wedding (that day) or graduation etc. and they needed a new battery. Well if their camera took AA/AAA's or even a lesser common CRV3, they'd be okay. However, a majority of camera out there take their own unique batteries. Plus AA/AAA's come in rechargeable forms as well (plus they are cheaper) or the non-rechargeable lithium version.
Most of the Canon Powershots are good cameras. My previous camera was one and it was pretty solid...only to be abused by some people I loaned it to and thus requiring me to get my new Fuji S8000fd.
