Can anyone recommend a good whell or optical mouse, the new mouse i just got the labtec optical 800 is not very comfatable at all

i'm also looking at a new mouse mat, the cheap one i got at moment is just too small, on play.com they have razer and cyber mouse mats that look quite good

I've got a Microsoft Wireless Laser Desktop 6000, and it's a pretty comfortable keyboard/mouse set. I use one both at home and at work.
