This one replaces my 20 year old preivous one. I'm impressed with the dough hoook. I use it often to make luscious cheese tortas, prepping vegetbles for soups and stews. I just made a Martha Stewart sour cream coffee cake in it, very efficient. Although expensive, it's worth it for variety of tasks using the disks, and it's so longlasting.  The recipe booklet has a lot of interesting recipes and demonstrates what this machine can do.
