The thing about cutting mats in an electronics lab is that you're never going to be cutting anything big. You're going to be cutting a lot of small things. So the small, dirt cheap, easy to move around ones are perfect. A rare example of cheaper being better!
Yep, exactly. I can see the value in large ESD-rated full desk-covering rolls though, if you've got the cash to splash on it. (But certainly not in a hey beginner here's how I think you should set up your desk/lab type article or anything.)
