Best mouse mat I've every used for my MX700 is the one I'm currently using.
I'm not sure if everyone around the world has them, but you know those Green Material bags you shop with instead of plastic bags? They have that hard bit of plastic in the bottom to keep it square...
That - It's
perfect.
The way an optical mouse works is by sampling the 'image' (interference pattern) it picks up from the laser - So, by having a very irregular pattern (ever-so-slightly rough surface) that isn't shiny is the best solution.
I've never
ever had wandering cursor syndrome with my optical mouse... Even when I was using the worste mouse mat (Shiny, polished, pure white desktop), the only problem was with accuracy... Never wandering
For those that don't have those green bags - In your Sport Bags (Footy Bags, etc), the black bit of plastic in the bottom to keep it square - Same stuff!
The Green bag ones are best, though, as they are the perfect mouse-mat size
Hope it helps you out.

Not quite true...
If you look closely at your lazer's receiver and the laser itself, there is dust build up... If you clean it occasionally with a lint-free cloth, you'll notice a MASSIVE increase in accuracy with your mouse
