Panerai PAM328 - A few questions

[DubaiJohn]

Well after a fairly long search and many trips to try out various brands I have more or less decided to push the button on a Panerai Luminor 1950 PAM00328 (it was a close run thing with a B&R though), but I have a few questions for the PH oracles.

1) This model has the inhouse Panerai P.9000 movement, does anyone have any feedback on this movement and how it compares to the earlier OP movement?
2) Any ideas where to source from on line. I have tried Jura, watches.co.uk and watchfinder.co.uk and blowers.

I have a price so far of the local equivalent of £4,700.00
