I can't say how excited we are about this little grinder attachment.  Of course I've used and loved my KitchenAid mixer for years and years... why didn't I know they had a grinder attachment?!  We are hunters and cannot wait to process the usually wasted deer and elk scraps (not to mention everyday meat scraps) for healthy dog food for our 4 dogs!  Our first grind was a large London Broil that ended up being the BEST taco meat... I highly recommend getting one of these if you have a mixer.
