The reason anybody doesn't like the KA for mixing doughs is they don't understand how the dough hook works. They don't realize that when the dough pulls up onto the hook, it's still being kneaded. If you want, you can push the dough off and start the machine again, but you don't have to.
My biggest gripe with the new generation of Sunbeam mixers is that they're made in China. I don't know about you, but I much prefer to keep Americans working in American factories instead of sending the money overseas and the American worker to the unemployment line. Aside from the global economic issue, I have gathered from reading other boards, that Chinese made kitchen appliance quality and reliability is spotty at best. If you're lucky, you'll get a good one. If not, your appliance will break soon after the warranty has expired.
My KA is pretty close to, if not more than, 30 years old.
