The fact that the tech said diaphragm regs are better in your waters
suggests to me that he may not have been a "genuine" Scubapro tech since
they tend to be fanatic believers in the balanced piston design. The BP is
a perfectly respectable design with a great track record, and salt water is
salt water - there is nothing unique about your waters that should make the
SP BP a worse choice there.

So you might want to seek a second opinion since techs can be quite
chauvanistic on diaphragm vs piston, and devotees of the diaphragm find it
difficult to believe a piston reg can work at all, and hence are often
quick to condemn them when any little thing is wrong.

I have seen damn few regs that were truely unsalvageable, and find that
most of the time when a tech says a regulator is beyond repair that the
real problem is the tech isn't qualified on that make, or just doesn't like
it.
