Have you tried the Kenwood yet, Katherine? I bought one at Costco too and I really wanted it to work. But when I was kneading four Modern loaves, it overheated and needed a little rest. It started up again shortly after, but since I was buying a new mixer, I really wanted one that could easily handle four of our loaves. So I returned it and got a pretty yellow Ank from Bread Bekkers. With the $100 discount and no sales tax, the cost was the same.
