Just to add a data point:
http://www.reef-fanatic.com/calciumreactors-co2.htm

I just picked up a dual regulator, solenoid, and needle valve from these
folks for $159 to replace the aging Sandpoint setup I had. I works well at
only 3 psi to the needle and the solenoid is much quieter than the old one
that ran at tank pressure.

I still like the old Sandpoint powerhead driven reactor, I haven't seen
anything else like it. Of course, I'm kinda a glutton for punishment pumping
CO2 into an open top 225 gallon, but I get a couple months out of a 5 lb
bottle anyway.
