I too was in the market for a camera last year and did "extensive" researh on anything and everything I could get my hands on. I read many reviews and frequented review websites before finding the perfect camera for me. A couple of great sites were already mentioned by a previous poster, dcresource.com and steves-digicams.com. Both are excellent sources of information.
I ultimately chose the Canon Powershot S70. It is without a doubt an excellent camera for someone looking for a little control in the pictures they shoot. It has all the features an avid photographer would want without getting into Digital SLR's. If you are intimidated of all of the features available, just put it in auto mode and the pictures will turn out unbelievable It's a 7.0 megapixel camera that takes breathtaking photos. I can't recommend this camera enough. Do the research and you will find that this camera is right up there in it's class. For around $500, you will get a camera that can last you many , many years.
I definitely would stick with Canon with whatever you chose. Can't beat their quality!!!
Hope this helps!
