do you have some special mouse and keyboard for gaming. what are the pro's and con's and what do you really like in your mouse and keyboard.

for gaming i have Logitech G5 - it's very good and ergonomical, but the third mouse button (scroll click) is unsecure what means that you can scroll at the same time you are trying to push the button and thats not good. laser is very good - havent had any flicks like with ordinary optical/not laser mouses where you start to spinn around very quickly sometimes

keyboard is ordinary logitech's (10 years old) wireless dont even remember the model no. pretty plain keybaord and nothing special about it

why i'm asking these questions is that i want to replace my 10yo keyboard for a new one - so give me some suggestions.
