Regarding several thousands for a replacement.. to be fair, garage doors are probably one of, if not the most, dangerous part of a home to work on

Sure, but that's if it needs a replacement. OP didn't.

I had the same happen with a toilet; the float needed replacement, but the big plumbing firm claimed it'd be better to replace the whole toilet. Toilet was fine.
