I need a new mousemat and I want a particular type. The scattering of bricks and mortar shops near me which sell such things only have those crappy small fabric/plastic ones with various film characters printed on them, so I shall have to buy from the internet. That means I can't inspect the mat to check it's what I want, so I was hoping someone here could recommend one which fits the bill.

I want a mat which is:
-The same size as a sheet of A4 paper or a bit bigger. Not one of those A5 wastes of space! I hate having the mouse fall off the edge of the mat because I wanted to scroll more than half a screen.

-Smooth finish. As in, sheet of paper smooth. No fabric texture, no grain, nothing.

-Suitable for use with an optical mouse.

-Not ludicrously expensive. Some of the mats I’ve seen which might fit the bill cost more than a freshly released game!

Right now - and for the last couple of years - I have been improvising with ... one of those lined A4 paper refill pads. Seriously, it's the best mouse mat I've used in 15 years. Perfect size and finish, just not durable and quite prone to giving me fine papercuts on the inside of my wrist.

Thanks.
