That is like one we had on the farm for grinding maiz or field corn. I don't remember how adjustable the one I used was but for $20 on ebay you can find a cornona style mill that some people swear by. I've even seen some that power their corona mills and wouldn't trade them for even Yuri's over the top roller mill. Well, I bet they'd trade their mill for Yuri's but his is truly a one of a kind that could probably crush granite gravel into sand.
