and

Best Sony Camera $ 400 - $650 : Sony Cyber-shot DSC-N2
and Sony Cyber-shot DSC-T30

Good luck

I was just given a Sony DSC-W55 and highly recommend it. In less than an hour I had figured out how to take pictures and movies. It was a snap to download to my computer. This replaced a 6 yr. old Kodak and the difference is like night and day. The screen is huge and when you choose a setting it comes up in large letters on the screen...so you can read it. This is a wonderful camera for beginners and pros.
