Sorry I can't directly answer your question about PCX upgrades but I would imagine Firebat may have a point when he says some people underestimated the break-in time for their upgrades... I also agree that Ckoffend makes a good point about the actual upgrade cost when one considers integrating a repair process at the same time.
As an extremely happy Line 3 owner which I bought new before SF went under AND with several "custom upgrades" [done at the factory as per my local S/F dealer's direction] I couldn't be happier with its overall performance and reliability. Servicing is still available at SF/Anthem though I doubt they do upgrades???
All I can tell you is that other components have come and gone over the years but for more than a decade my Line 3 is and will continue to be a staple in my system.
FWIW they are a steal on the current Audiogon market when they do pop up.
Good luck
