Apparently, that's no longer the case. (My template for judging what things should cost was set in the 1980s. Every December, I'm still somewhat shocked that Christmas trees don't cost $12 anymore.)
After some searching, I found this Kenwood stereo receiver at a second-hand shop for $40. To describe it as solid-state would be an understatement. You could knock a rhinoceros unconscious with this thing.
