I received it Saturday. I purchased the MM2, hopper and base. I opted not to upgrade anything (SS rollers, 1/2" shaft). I talked to the guy at Monster and he said "as is" the mill will easily crush 10k+ lbs of grain before any noticeable wear is noticed. I am ok with that.
It is a heavy duty piece of equipment. The hopper and base were 35.00 and it is well worth the investment. The hopper is very very nice and big........ it assembles with machine screws and nylock nuts. The base is made of MDF and is also nicely routed.
For 150.00 shipped to my door, I could not be happier with my purchase!
