i find olfa mats much more expensive than other brands, but you really dog et what you pay for. i have gone through three fisker's mats in the time that my olfa mat had been around. actually, i've had the olfa mat for a coupleof years longer! it's just not as big as these cheaper fisker's mats.
anyway. what i am trying to say is the olfa mata re worth the investment if it won;t hurt you to shell out the money up front.
