We've been using a Quilt Cut Pro for all our shop production cutting for over 5 years now. It's well-made, does what it's supposed to do, and really makes production cutting easy, fast and accurate. It also makes cutting a lot safer than with using regular rulers. About the only thing we've done is added the Invisi-Grip non-slip plastic to the bottom of the rulers to make it even better. The one negative is that the Altos mats are not self-healing, so they need replacement once in awhile, but that's probably not a large consideration if you are using the cutter on a small-scale basis and not making hundreds of thousands of repetitive cuts.
BTW, we also bought the bolt rollers and have rarely used them -- so if anyone needs one, PM me for a good deal on one or two of them. :-)
