I would get a no-date sub. 5512 or 13 if you can find a good one or a 14060 before they muck it up any further with their new clumsy case.
While I really like the 5513 for many of the same reasons that you name, I ended up with a 14060 as I wanted to buy new. In the nearly 20 years I've had it, it's taken quite a beating (I even cracked the crystal once, but that was my own damn fault). It's currently at the spa, for what I believe is only the second time in all those years.
