I've had a Zojirushi and a Breadman. Neither ever walked.

FWIW, I liked the Zojirushi much better. It did a better job kneading and proofing the dough, and handled heavy rye and whole wheat doughs better than did the Breadman. Also, the Breadman used a yeast dispenser that added the yeast after the batter was mixed, instead of with the liquids as with a conventional recipe. The texture and rise of the Breadman produced breads was never quite satisfactory, and I have wondered if that was one reason.
