What happened to it? In what way did it crap out?
I have the Motorized Malt Muncher Pro from Morebeer. I really like it, but recently the axle that's welded to the roller completely sheared off. No more rolling. I was pissed. Only three years old, but in these years I've used several bags of Bairds MO that, unbeknownst to me, had jagged, peanut-sized rocks in them (thanks, Bairds), which jammed the rollers and undoubtedly stressed the metal.
Fortunately, I have a backup mill (ironically, a Barley Crusher) from my earlier days of when I didn't brew as often. Hate to suggest this, but a cheap second mill is good insurance.
