Did a bunch of research a few months ago, and decided on a Logan 450, but before we made the plunge, we inherited an old Altos mat cutter. Don’t use it nearly as much as we thought we would, and buying mat board a couple of sheets at a time is practically impossible unless you live near a large art center, so that helped to rule out eventually buying the Logan.
The thing I like about Logans is that the cutter slides on rails, while the Altos do not. We’ve made do with the Altos, but I let her do the actual cutting. I doubt I could keep a straight line.
