Nice 6 year dumpster dive, Annie. Always leery of a 3 time poster making purchasing recommendations. And Robot Coupe is way too much food processor for anyone who's not cooking commercially. Bad call.
A good manual meat grinder can be had for $30 or so. If you're bound and determined to grind your own meat, it's less than the cost of a night at the movies for two. That said, if you frequent a decent butcher, it's not hard to have some good meat ground for you on request. Even my local Giant food will do this without any griping.
