I agree with the first responder. When companies continually to discontinue products, that means that they want their products continually reviewed by magazines and they want it to seem as if they are coming up with something new and better. Seriously, it just doesn't work that way. The science really doesn't take leaps and bound improvements. It comes rather slowly. The circuit designs have been around for quite some time, with subtle improvements here and there. Various manufacturing techniques have arisen that improve quality and also newer parts that are better made. However, I do have a problem with companies that discontinue equipment quickly.
