ok, i am a DIEHARD 1.6 gaming fan, so if you ask my opinion its going to be biased and im going to tell you to go with a very expensive pad called the steelpad 5L which you dont need, but i will be nice and link you to a VERY nice pad at a VERY reasonable price.

cough might still be a lil biased cuz of the cs 1.6 pic lol. They also have an hl2 pic, but its outta stock, and if you dont like pics on your pad i can reccommend you another, but as a pad in itself thats a very solid nice pad.
