Hi,

Please keep in mind that new and used nsr parts aren't always easily obtainable especially if you live in the middle east or gulf states. I was looking for ages for a pgm III and then opted to have mine repaired by a guy in Greece and my rc valves worked fine. I then bought one from Japan and that has never been used and sits as a spare.

It depends on what is faulty with the pgm?

I have seen a few for sale so you shouldn't have to worry about sourcing one.
