I'm not a fan of automatic sharpeners .there is alot of plastic in the machine. Skate sharpening is easy to learn.
I can get you a professional quality sharpener for $ 1850 with travel case ,edge checker, honing stone,took kit . It weighs 65 pounds in the case . The thing to do is have your close hockey friends go in on it . 8 friends go in on it and it pays for itself fast . And when you sharpen your own it only takes a couple of passes to sharpen them . I use the machine as a professional SSM2
