I too would reccomend dpreview.com.
Some quick things to note:
**dont buy on the number of megapixels, look at sample photos and how good they look** You are taking pictures not pixels. In photography the end result is all that matters, how you get there is not important. My freind bought a plastic wierdo camera off ebay and it yields some interesting photos.
*Dont spend extra for digital zoom. It uses the same pixels and literally zooms in on them. It is obvious. Get optical.
Dpreview.com offers great comparison pics between models that you can look at.
