If you was going to buy a new controller would you get the cheapest or dearest? I can only afford knock-offs but are they really worth it? Would I be better off buying an official Sony controller? I have bought a knock off quite recently as the two back triggers had dropped after taking the back off. So when I recieved it there was immediately 2 problems. One is that the analog buttons are stiff. Maybe not such a big one as they can be broke in but still annoying for COD. Two the L1 button is dodgy. Sometimes it works other times it doesn't. I find that I am pressing down on it harder than I should which is not good. Maybe it just needs runnning in? I think if I do buy a knock off I will make sure it is a wildcatz controller.
