I have the Classic and make bread with it. No problems. I do stop the machine every so often, because I can feel the motor getting warm. But I am never in a rush so time is not a problem for me. And I would rather finish kneading the dough by hand. I think you need to get your hands on the dough to be able to tell when it is done and ready for rising.
For those who find that you have to stop the machine to scrape down the sides a nuisance, KA sells a paddle that is superior to their standard one. I highly recommend it. I have one and the one that came with my machine is growing cobwebs. Stopping the machine and scraping down the sides was a constant source of irritation to me. It gets all the ingredients in the bottom of the bowl also.
I remember the original Sunbeam mixer with the controls on the back end of the head. The beaters stayed stationary and the bowl turned. You could adjust the bowl to sit offset to the side. No problem with scraping the bowl down.
Illegitimi non carborundum!
I don't want my last words to be, "I wish I had spent more time doing housework"
