In other words what is your favourite mouse that you have used/tried?
Mines : Logitech MX518
Edit: Include your mouses buddy the mouse mat :P
I'm stuck using a generic dell mat. But am interested in getting a mat that won't wear down as I had a everglide soft mat.

I`m using a Logitech MX510. I think this the best mouse for playing shooter games like Counter-Strike or Battlefield. A good connection to this mouse is a Steelpad (http://shop.esl-europe.de/product_info.php/cPath/25_40/products_id/56) a very good mousepad.
