I used to have the soft Gel wrist support mouse mat, cheap from pcworld brought 2 of them lasted just over a year for both of them.
very good for laser mouse nice smooth non grip surface, But now I have a large screen I sit back in a chair and place mouse mat on the bed next to me so I went for a steel allsop mouse mat. It stays firm on the bed and the mouse glides on it. Only point to make is they use very shiny smooth surfaces, you would need a good high dpi mouse to cope. My MX Revolutions copes well no glitches at all
