I have the mat from cutting-mats.com. I have had it for 2 years and so far it is great. Mine is 3x4. I haven't had any problems with it. I used to have the clear one from JoAnns. After 2 years it was shot. The area on it where i used it the most got all messed up and I couldn't cut in some spots any more. Sounds like an awesome cutting table. My table is 4x4 and it would be a lot nicer if I would clean all of the junk off of it.
