Which camera should I buy my girlfriend?

[Steeve]

24MP in $ 200 will be a bit difficult. I suggest Sony DSC-HX50V/B as it is a great cam and it matches oyur requirements too. It is a 20.4MP Digital Camera with 3-Inch LCD Screen.
Here is a review of a professional photographer, i hope it will help your decision:
