the cost is more in power to drive tht thing instead of $$ 
the reason they use them (aiui) is becuase
a) springs have material limits and a lot of inertia
b) the force applied by a spring decreases as it extends.
the pneumatic spring has less inertai, and has a pretty constant force, so you can yse much larger, more aggressive ramp rates, and still keep the valve in contact with the back of the lobe.
pneumatic doe snot open them, there is some work into using solenoid operated valves, but again the power cost to drive them is very high...., heck even fuel injectors use abotu 1amp, and they only move a tiny pintle a few mm...
