I think it was the GE Super Radio II that started the "good" reputation. I bought a GE Super Radio III, and I was not impressed. But they are not expensive, so I guess you get what you pay for.
Build quality was poor. All the switches, and knob controls felt cheap. It doesn't even have a digital tuner, but rather an analog slide-rule type tuner display, that was way out of alignment. It has a very large speaker, but it seems to have a muddy sound. I had to adjust the bass to its lowest point, and the treble to its highest point, to clearly listen to a local talk radio station. I think it's highly overrated, maybe because it doesn't have much to compete with.
