I got one of these http://www.northerntool.com/shop/too...Product%20Page
just last week. I haven't had time to use it yet but, I plan to do so this weekend. It replaced the Northern Tool branded item. Same thing actually with maybe slight improvements if any.
I have a Cabela's 3/4 hp for big jobs but, wanted something better than the Kitchenaid for grinding my own beef(burgers). I got mine practically free using points I had accumulated. Check Amazon.com for their prices. Gotta consider shipping too.
