Well... my mouse mat is the same I use for ... 22 years I bought it when I bought de Commodore Amiga, by the time I was 13, and believe me.. looks the same when I bought it and by the time it cost 25€.

But for real, for gaming I bought two mousemats from razer, the speed and control ones, well, i end now using the speed one under the keyboard, as it takes out the noise the keys do and the desk cold, under the razer i've put the control, they-re both nice and BIG.

EDIT - Vogon know more of my hardware than me )
