For 1982 it was pretty fine & top of the TEAC CX- line. The features are fine and comparable with that era. Mic inputs are a plus, as is 3-head design. Independent input/output level controls are nice. Big VU meters are nice.
It's maybe not as super slick as later 80's designs, but is pretty solid in features. It's way better than the junk built in the late 90's.
Mixdown to cassette is a bit outdated, but it's fine if that's what you play around the house and in the car.
Vintage 80's decks might require a little maintenance for issues related to belts that affect speed, wow & flutter, etc., but there's no predicting what you'll come up with. You just have to try it and put it thru it's paces. Many 80's decks might have no issue with rubber parts or maintenance at all. It goes on a case by case basis, and is just something to watch for, not always requiring maintenance as a rule. I have many 80's vintage decks in original condition that run fine. Good luck.
