Thanks, Jen. But I think that if I can continue to get replacement blades for the one I have (which also had a protective film that I didn't realize was there until it started to peel up!) I will just stay with it. You have to swing the arm out to get to 5.5 inches so you can cut the paper in half, but I've been doing that all along.
I ordered a Tonic guillotine cutter to use for my heavier CS and I'll just stick it someplace not too inconvenient. It won't be right on my worktable for now, but I've just reached that point of critical mass of stuff on my worktable and I'm going to have to rethink how my studio is arranged in any case.
