Query: Terrific customer service but go with the 750!

My stupid feeder locked on me and refused to recognize the food in the tube. Kitchenaid said that this was a problem with the lid and sent me a 750 lid and Voila! the machine finally worked. America's Test Kitchen also recommends the 750. They are the same machine but the 750 also offers colors. Dang!If not for owning a food processor, I would never shred cheese, use up leftover lamb for tastier lamb and onion meatballs and make rugelach dough with a stick of butter, a brick of neufchatel cheese and flour.
