We grind a lot of meet here at home. And have had them all I think.
If serious and want to do like whole pork butts for pork burger or home made sausage, the volume and speed of the Lem line is awesome
Number 5 is perfect for home, all stainless and has all the attachments to stuff sausage should you go that way
We try to grab sale briskets and sale Chuckroasts for burger 60/40 chuck to brisket is so much better than anything in store ground. For now, sale meat will not be a thing but in time it will come around
