I've had Sharp and Panasonic, and we have a very big Panasonic at work. I would be looking at Panasonic if I was shopping. If you got 25 years out of a microwave, you're very lucky. 10 years seems to be about how long mine last. They don't die, they just start to fade away and get weaker and weaker. When The Sharp finally got to the point popcorn was iffy, it was time. It was almost exactly as old as the dog in my avatar was, 14. It had been fading for some time before I decided it had to go. I don't know why I waited so long.
