Dryer
I have that dryer. It's got very accurate controls, you just set it at that star and hit the button. No buzzer or anything, but it works well. And will probably run forever.
The washer-----I wouldn't want it, true, but as a college kid it would have been an improvement over carrying laundry baskets to the bus to the laundromat. I would have loved it. It would be easy to turn off the cold water at the start to get a hot wash, then just turn the valve back on once it fills, you'll get your cold rinse.
I bet Sears priced them right in the day.
