As I mentioned in the other thread, I own a JSP Model P and a 3-Roller Monster Mill. If I could only keep one mill, it would be the JSP. What the JSP lacks in bling, it more than makes up for in tolerances and durability. There's significantly more play in the bearing surfaces on the Monster Mills than there is on the JSP mills. The bearing plates need to be aligned carefully on a Monster Mill or the rollers will bind.
