My Company adds the 50' to ALL non-precision approaches i.e. VOR/LOC/NDB for the reasons stated already many times in the thread. We have twin GPS fitted to our NG 737s, but although Boeing recommended flying non-precision approaches in LNAV the Authority does not yet allow it. With P-RNAV approaching rapidly we are likely to be able to do so in the next few years, and VNAV is likely to be added too!!!
With respect to circling approaches, Salzburg, Grenoble, Nice, Funchal, to name but a few, spring to mind. Not to mention Samos which has a VOR approach at right angles to both runways, but Samos is another story....
