First of all, after reading your message, I believe the subject of

Recommendations? Other options?
I believe there is no easy answer for this. The two options you
mentioned have issues -- not the performance issues you expect, but
things that don't work. I therefore use a third option, which is to
implement custom setters so I can hook into them and post my own
notification.
The additional issues which you have not discovered yet are explained
in these threads:
