We had one of these for recording with a band I was in way back when. In the 80s they were highly regarded as flexible home recording desks. There are lots of buss mix options and the preamps are nothing special but plenty usable and I think it had sweeps on two of the EQs. We had some kind of funky wiring setup that allowed the use of the four mix busses to feed an 8 track reel to reel. The thing that makes it kind of outdated is the use of RCA jacks for everything except the mic inputs. No phantom power either IIRC. Sounded pretty good for a home studio setup back then with just dynamic mics and no outboard gear. VU meters
. We used it for tracking and then the other direction to mix down to two track.
What do you plan to use it for?
Also, I wouldn't pay much for one of these. <$100
