Need Advice- PS2 Controller Question

I want to get a wireless PS2 controller to play my new game, but I am not into the video game scene and was hoping for some advice.

Which PS2 controller should I get? I went to Best Buy’s PS2 controller page and there seem to be several options. One is 20 bucks more and I want to know if a moderate gamer like me would notice the difference. I don’t want delay between button pushing and character reaction, so if anyone could recommend a controller, I’d appreciate it.

I don’t have a PS2, but you might take a look at the reviews of some people who seem to rate this kind of thing for a living.

Probably the Mad Catz one, although it’s not as good as a wired controller. The logitech one is waaay to big, especially if you’re used to the standard controller.
