Haven't used that one, but I think I've seen it, and it looks like a good one.

With any of them--keep lots of extra blades on hand, and change blades often.

Every time I do a large mat, I change blades, and if I'm doing 11x14's, I change every few boards. I use an old-style Dexter mat cutter and t-square, so you might be able to make a blade last a little longer if you have a more heavy-duty setup with a cutter that is fixed to a channel on the straightedge, but blades are cheap enough that it's worth it to change often and get clean cuts every time.
