Olfa for me, too. I just replaced my 24 x 36 mat after 11 years of use. They are pretty expensive but using a coupon at Joann's helps. Even though I usually get aggravated when I try to use coupons at Joann's, they do help. There is usually some reason why you can't use the coupon you thought you could use. I had a 50% off, but they were on sale for 40% off so I couldn't use it, and since I had gone out of my way to go by there and get it, grrrrrr. (but I digress) Go for the Olfa.
