All depends on budget and how much sausage you think you will make, or more specifically how often.
This can be a real rabbit hole money wise, but I would suggest a grinder in the #8 size, you will have to decide if you want a more commercial built or more of a home kitchen built unit. (I run the commercial #8 from LEM)
You will need a stuffer. I suggest the LEM 5# manual to get started. Although I’m running the 10# electric version but I have had the 5# for many years.
I suggest also to buy from a reputable company and not so much just off of
Amazon or other market places. You want good CS backing up your purchase.
If you jump in, welcome to sausage making. The knowledge here for sausage is about the best there is on the webs. Just go to the sausage sub forum and ask any questions.
I also suggest any of the books from Stanley Marianski. One of the best references out there on the subject, besides here of course.
