Au Contrare, How does $100 sound?  I don't recommend running 20 psi
but "The Knob" can dial in whatever you dare to use.  I think 13psi for
the later 20 vavle motors would be plenty for most people anyhow.
All the comments about reinforcements are right on track.  It takes
more than just turning the screw.
