Sony DSC-T5, DSC-T9 or Exilim EX-S600

[Cinae]

Hi all,
i'm new in the forum but i like the reviews. I'm going to buy my first Digicam, but don't know what's the best choice. My favorits are

-Sony DSC-T5
-Sony DSC-T9
-Casio Exilim EX-S600

The size of the camera is very important for me, because I would often like to take the cam with me. Also important are still pictures. The quality of the motion pictures don't play a big roll for me. Which of these cams has the best still picture quality?

Casio has the Anti Shake system. I've heard it's only increase the ISO and isn't a right stabilizere.
I think the main difference between the T5 and the T9 is the stabilizere. The T9 is more expensive in relation to the T5. Is the stabilizere the money worth?

I hope you can help me, cause to buy the first cam is a hard decision .

Sorry for my bad english, i hope you understand everything. Should be something not clear, please ask.
