How expensive depends on what kind of junk you have available for reuse. If
you have an old regulator from a gas grill, and a 1/4 inch pipe nipple, it
might not cost you anything.
I like your web site. Do you use the sintered glass diffuser on you high
pressure system to reduce your flow rate to about 1 bubble per second? An
automotive air conditioning capillairy (sp?) tube before the bubble counter
(high pressure system) might work too.
