First off, this person is not "us", those that rebuild their own gear. 2, I would not dive it without, at a minimum, replacing the 2nd stage seat (along with all the o-rings obviously) which Dacor does not make. 3, the 360 was an "ok" regulator to begin with.
I pick up a 1989 Apex TX 50 (or an SP G250), in the box, all the hoses would be replaced, I would put brand new 1st and 2nd stage kits in it then I would dive it.
By the time the OP "does it right", she spends a lot of money and she still has a Dacor 360...... just say'n.
