I have a grinder and I have ground pork through here all the time. My wife is Filipino and uses it and anchovies in a lot of her dishes. I can flavor the pork the way I like, I even have mixed in ground lamb before. Its getting it in the casing the F's me up each time.
Closest butcher that is of any quality to me is a little on the expensive side; but if I am cooking for just friends and family I am all over it. This is more for when I'm cooking for groups of people. IE Scuba buddies when I teach a dive class or at a church function or something. I do not like to serve anything that I do not myself like.
