I bought one about seven years ago, it takes a while to pay for itself. But it's worth getting one for the convenience, and if someone asks for one there's no hesitation. Just grab it out if your garage, and there's some good money to made with these.
That's what I was thinking. 28 cutters are useless and I'm always working with it. I really like my digi manometer also that's built into my Anton also. Makes things very easy
