You need to find a secondhand Hobart N-50. That will handle anything
you can throw at it. They are expensive, but well worth it. I do not
have one, but I know folks that do. The other machine you should look
at is a 1000 watt 7 quart Viking mixer. I have a 6 quart Professional
KitchenAid which I love. Those are all the options I can think of at
the moment.
