I have a KitchenAid and I must say, they are as good as their high reputation. I bought the mixer mainly to make bread, but what makes it even better are the accessories. These convert the stand mixer/dough maker into a vegetable processor, grinder and sausage maker. There is also a grain grinder that really works quite well. Here are the pros and cons of this set, as I see it:
You get a decent meat grinder with two blades, coarse and fine. This means you can make ground turkey with no additives, ground chicken without added fat, or fresh ground beef. You can also grind meat for sausage (about which, later.)
You get a slicer similar to those hand-turned cone types that make cole slaw or waffled carrot slices.
The sausage nozzle for filling the casings is not included. This is, in my opinion, really dumb. It's just a couple of pieces of molded plastic. For heaven's sake, include it.
The slicer is a bit clunky. If you don't put the bowl to catch the shreds just right, you get slaw all over. And sometimes it is hard to get the cone off the flanges of the connecting pin that fits into the mixer attachment point. But screwing it into the mixer and grabbing with a rubber mat usually works for me.
I prefer a mandoline, a food processor or even a big board and a really sharp chef's knife to the slicer, but it does save on counter space. So, this is a good thing to have as an addition to your KitchenAid if you do any kind of prep cooking, such as canning, salads, baby foods, venison processing, or sausages. It's very good quality plastic and metal, though the cone blade finish seems a bit crude to me. I can recommend it, with the reservations I mentioned.
