I still have one of these buried somewhere in my many piles/boxes of radio related stuff. It was small enough to be placed into my 1990 Toyota Corolla, along with a Radio Shack CB. If I recall correctly, it was also the scanner in the "command vehicle" in the movie Universal Soldier......with Dolph Lundgrens character tuning it at some point, mounted to the dash of the semi tractor. (Always wondered how it would fair being mounted up high on the dash like that).
The rubberized buttons were a bit annoying, and the two digit display would scroll the frequency programmed, which at the time I thought looked cool. But now I prefer seeing the entire frequency display at once, LCD's made this cheap and abundant. Would have spent the $4 too, I bet it still works.
