I really hate to say anything about Wolfgang Puck because it is totally not his fault, but I ordered his really beautiful food processor from HSN, TWICE! Both times it was used, with debris left on the blades!
So, I decided to order the KitchenAid 760 B and it is almost silent, chops, shreds, purify's, and pulverizes anything you put in it. The extra wide mouth on the food shoot is excellent for potatoes, zucchini, and large vegetables. So far, nothing I used in it slowed the motor down.
The use is simple and easy to put together and it cleans up beautifully with everything encased, leaving nothing open for food to get stuck. One spot may be the spindle which turns the blades, but it wipes out very easily.
The attachments which come with it along with the blades provided are enough to do anything you need. I've made bread dough, and being a vegetarian, used it to chop every manner of vegetable, effortlessly. Worth every dime, dollar, hundred dollar, two hundred dollars!
