I’ve been there several times. The prices (as far as concerts go) were not bad - I would buy a subscription, and everyone would divvy up the tickets and pick an opera. The NYC opera had light opera - I remember attending Die Fledermaus the night Clinton won the presidency.
One of the things I really liked about it was that it had subtitles! It ran across in a dark blue band above the stage, so it wasn’t invasive, and you could tell what was being sung. Opera is really fun to go watch, even if you don’t listen to it.
