I would recommend that you 1. decide what it is you really want to do with your camera. 2. After that, ask questions about the strengths and limitations of the cameras you are interested in.

Hopefully it will lead you to buying the best camera for you. You don't want to buy more camera than you need. I have been doing photography for more than 20 years. Two years ago I decided to go digital and bought a Nikon D200. I am still learning how to best utilize all of the features the camera has. Don't skimp on lenses either.
