Day-Date 40 shortage in the U.K.

[Gazza67]

I recently decided to look at adding a DD40 to my collection and thought that this would be readily available so was surprised to be informed that these are also difficult to obtain.
I have been informed by several ADs that the wait could extend as much as 2 years and, due to the shortage/Rolex policy there is no chance of any discount!
I was of the opinion that it was possible to get a decent discount on a PM model - I have always understood that this was the case for SS models but is that now the case for gold models as well?
I would also appreciate some input on how this wears as I have not owned a gold watch before?
