Rather overpriced, IMHO.
I once scored a TAPCO vintage mixer- it was actually a main board, with the output side and 6 input channels, and an aux. board with another 8 inputs. Yep, 14 input channels- wierd. Both pieces were rack-mountable, and the board came in a "coffin" case. My son took the case during his DJ phase, and I kept the boards, which were 90% functional (one input channel was dead), albiet with some very stiff pots.
I paid something like $40 for the whole setup, and sat on the thing for a couple of years. David gave me an old-school, fully functional Yamaha powered mixer in exchange for the case, which I sold for a bit more than I paid for the TAPCO, and finally sold the TAPCO, plus a home-built 150-watt power amplifier, to a kid in the neighborhood for $20 so he could mix vocals for his garage band.
