The bottom for Technics that model run is the SA-80. The SA-200 is second.
This is an SA-200.
The SA-80 can be had for $9 to $20, the SA-200 for $20-$30, average.
A nice piece of kit, but for that $100 you could easily get an SA-400 (a few models up), to an SA-700, maybe an SA-800 if you were extremely fortunate. The EQ is worth $20 to $30, tops, most likely.
