Hi Guys. This is my first post to this board.
I used the kitchen aid attachment a couple times but was rather unimpressed. While it's fine for grinding meats with good marbling, it was unfit for long use with denser venison, IMHO. I wound up getting the all stainless #22 1HP tre-spade grinder as a factory refurb from weston supply and have been quite happy with it. $288 to the door. BTW, northern tool is selling 5# vertical stuffers for only $79, everyone else wants $129 or more for the same stuffer. They also have 44# mixers for $200.
