Re: [APD] cheap pressurized CO2

Eli,
I tried to do the pressurized CO2 cheaply too.  I got a regulator thru 
ebay from someone selling it in my own city - no shipping cost.  Then I 
got a needle valve thru ebay from someone very close, so shipping was 
minimal.  But, when I started assembling the stuff together I needed 
barbs, special size barbs to fit the valve and regulator.  Those I had 
to order on the web, and pay shipping for them.  And, I still didn't 
have a bubble counter, so I made one cheaply.  The tubing I needed came 
from a model airplane store - fuel line tubing, cheaply.  But, still no 
solenoid valve.  By then my cost was up over $125 for an incomplete 
setup.  I gave up, gave away the parts, keeping only a check valve, and 
bought a Milwaukee regulator/valve/bubble counter on sale from 
Aquabotanics, and that cost was far less than $125.  I'm not  yet 
convinced that a "cheap" CO2 setup can be built.  Maybe someone here 
has a surplus setup and can be convinced to part with it for minimal 
cost???
