I own a non-adjustable MaltMill (my second) and an MM3. If I had to get rid of one mill, it would be the MM3. The MM3 pretty much collects dust. It was an impulse purchase. I put several thousand pounds of malt through my original MaltMill before selling during a hiatus from the hobby, and it still worked like new. The MaltMill may not be as sexy as the newer mills, but it has proven long-term track record. Now, dealing with Jack can be an interesting experience.
