I didn't buy the KitchenAid branded pasta attachments. I got the ones pictured below. Great quality and every bit as good as KitchenAid. I only got the roller and spaghetti attachments. I don't make fettuccini much, and that I can hand cut.
Don't buy a unit that is called a 3 in 1 Noodle Maker. They are hard to clean and don't work as well.
