I use this...I have had it for 10+ years. My table is actually 2'x8', so I cut it in half. Every 6 months or so, I flip it over and use the other side. Little pricey, but I have never cut through it. All of my large cutting is done on it. You can also buy it with a grid as well. I just leave it on the top of my workbench. It also doubles as a way to keep dye of my table top (a few spills here and there).
