There is a large price discrepancy in Robur burrs (71mm single phase). What is the deal? Are these all the same burrs? Were the three (albeit 83mm) burrs tested by hg-one http://hg-one.com/battle-of-the-burrs/
all mazzers or different manufacturers??? (they found a large difference in burrs but although they went with mazzers, it's unclear WHO MADE THEM) Do different manufacturers make mazzer burrs? Help!
Italian *bay: $77 shipped
Chris Coffee: $100
