Query: five stars - get a used one!

my wife got me one of these for christmas...after reading the reviews showing the temperature drops and quality issue of the made-in-china product, she bought me a used one (maybe 15 - 20 years old, idk) that was made in Tennessee. She says she paid about the same as a new one, but the quality is impeccable, the vacuum perfect, etc. It has some light scratching but works perfectly. I love it!
