My grandma had an original "Montgomery Wards" microwave.. they saved up for months to buy it when it came out. Complete with a rotary dial timer. Never serviced, always cooked perfectly. She had to get rid of it around 2006 or so, when she got a pacemaker.. They didn't shield them as well back then...
