Nice score Brett. You guys have tempted me to consider an upgrade, but I have certain restrictions from the boss ladies. A new grinder must: - be as easy to use as the current M4D. - be doserless. (non-negotiable) - have minimal grind retention. I have spent a lot of effort teaching my household to use our current setup. Single dosing with only minute grind adjustments was the easiest concept for all to master, so the new grinder will have to be easy to use. On the plus side, with so many shops closing down, there might be a unit or two available in the near future.......
