My neighbor has two of these, one in his basement
and one in his garage. They work great, and he's
had no trouble with them for 30 years! I've been
hunting for them myself, and the only link that's
come close is a company called Northern Tool. You
can find them at www.northerntool.com. Search for
Magic Heat. They're selling one for $100. When
he bought his thirty years ago, local hardware
stores were selling them. Now not even Home Depot
knew what I was talking about....
