I've had the Carl 210 for years and love it. I have yet to replace a blade and have only turned over/replaced the mat a few times - I do a lot of prep for stamp clubs and classes and it is ideal; clean, crisp cuts and can handle several sheets of cs at a time. I am intrigued about the Genesis, though - I'm a sucker for trimmers! I also use and love the Tonic guilliotine cutter and the Fiskers Triple Track trimmer.
