I have a Touchmatic from 1980.
It's the best microwave I have ever used. It has the big chrome door surround and the door opens down like a real oven. My housemates back in Savannah had a new $45.00 "Emerson" which was terrible. The only thing it would do consistently was screw up. It would pop half a bag of popcorn, burn it, and then leave the other half unpopped. I brought in my trusty old Amana and it just ran rings around the new one. We gifted the Emerson to a former friend and ran the Amana quite happily. Now the Radarange is in my basement awaiting my move to Boston (hopefully).
Warming,
