Commercial coffee grinders are periodically calibrated to ensure they are providing the proper grind. When new both the $100 unit and $700 unit would likely provide similar results. Over time the commercial unit (built to handle higher volume) would remain in-spec without calibration for a consumer user whereas the grind of the $100 unit would likely degrade from wear.
