Back in the 90s, I found one of these in a thrift store in the Sarasota area for next to nothing and in excellent shape. I bought it, cleaned it up and used it a bit, BUT like all of these, the big problem was that on 120 volts, you really did not get a lot of speed in combination mode because you could only operate the magnetron or the heating element. The answer to that was a 240 volt appliance with both modalities that could be used full blast at the same time to produce the 5 minute frozen French Fries under the broiler of my Amana micro-thermal oven in the 30" range. John was such a believer in this type of cooking that when we found one behind an appliance store in the 90s, he said I had to have it. We did not even take it off the back of his truck at his house but switched the brown panels on it with the white panels on a hi-lo Amana in his shop and then took it up to my house.
