About a year ago, when I was looking around for another mill, I considered JSP and Monster. But, from reading the JSP website it was apparent he was retiring and pretty much going out of business. I also just didn't want to do any fabrication to supplement the small hopper that was available. So, putting it down to personal preference and general laziness, I chose to go with a Monster mill.
I motorized my Barley Crusher several years ago when I decided I had better things to do than spend 15-20 mins cranking the mill. I was able to use the same motor set-up on the 2 roller Monster.
