Hi all, I need alittle help.

I have no idea what too look for within a camera! I am currently looking at one of three between:

Fujifilm FinePix F11 (When it's released, if not then the F10)
Casio Exilim EX-Z750
Sony CyberShot DSC-W1 Black

Can anyone make some suggestions for me, currently all I am looking for is a good make, high megapixels for £200 - £250.
