I have a Weston #5, picked it up at Lowe's for ~$80-$100 a few years ago after I got tired of fighting with the KitchenAid attachment. I actually enjoy using this thing (a lot).
I just finished grinding up a smallish pork shoulder I bought yesterday ($0.99/pound at Kroger this week) and portioned 4# of plain ground pork to save for my green chile burgers that the kids love and the other 5# went to bulk Italian sausage. From first cut of the pork to final wipedown was less than an hour.
Whenever this thing decides to give up the ghost, I'll probably just go buy another. I use it a couple of times a month with typical batches from 5#-15#, but have done some much larger batches during hunting season.
