Unicomp Model M. When IBM discontinued production of buckling spring keyboards the employees at the plant in Kentucky bought the factory, the tooling, and the rights to the (now expired) patents and kept on making the Model M the same as in 1985. It's a bit like how they kept making the original air cooled VW Beetle in Mexico years after everyone else moved on. They're nearly not as well known as they should be because they don't do any marketing at all. And at $104 they're not expensive by premium keyboard standards.
