Anyone run a Lemken Rubin?

Looking at a Lemken Rubin 10. Anybody used one of these or know how they compare to the more common high speed discs like Degelman, Kwik-till, JD 2680H, etc?

I would basically use in place of a mulch finisher in the spring on bean ground going to corn, with the benefit over a mulch finisher that it could be used in the fall as well on stalks.
