It might surprise you to know I've wanted to do the EXACT SAME THING -- start a company to make dead-simple appliances. I can't tell you how many 20-30 year old appliances from the 80s I've replaced in the last 2 decades, and the replacements are good for 5-10 years. I'd pay $1,000 for a washing machine TOMORROW if it had quality components (switches, motors, hinges, etc.), user-serviceable parts, and if it would last 50-100 years. No reason it couldn't. I don't care if it's a bit heavier and has thicker parts and is a bit less efficient, as long as it lasts. You know what's inefficient? BUYING NEW DAMN APPLIANCES EVERY 8 YEARS.
