Air Pressure Regulator (aka "Boost Adjust")

[rdh@sli.com (Robert D. Houk)]

Anyone have any ideas where I can obtain a small air pressure "regulator",
in the 0-10psi range? (One that might, say, be used by the more rambunc-
tious amongst us to offset, oh, maybe, a wastegate atmospheric reference
and thus implement a variable boost control...)

I was thinking maybe an arts/crafts/hobby store that might sell air-brush
systems (it seems like airbrushing would require a well regulated militia
er air supply to give best results) . . .

I'm sure such things are readily available, I'm just not sure where to
start looking.
