	I'm sorry that I can't help you with any "discount" sources for
such a regulator, but I can provide you with some other information.

	In my travels, I see CO2 supplied in K, Q and F cylinders which
contain, respectively, about 3, 20 and 60 pounds of liquified gas under
a pressure of around 830 psig.  A lecture bottle contains about 0.5 pound
of CO2.  I don't know of any 10 pound cylinders, but this may be a size
used in the beverage industry.

	I would use caution before trying a surplus regulator on CO2,
unless either you or someone with experience _knows_ that the regulator
is good.  A defective regulator could, under the right circumstances,
cause injury.

	Some CO2 regulators are electrically heated to prevent freezing
in high volume delivery applications; you may wish to bear in mind that
a non-heated regulator can freeze in a CO2 application.

	Also, beware that some CO2 cylinders are designed for _liquid_
CO2 withdrawl, and consequently have internal eductor tubes.  Such a
tank would be inappropriate for use with a gas-phase regulator.  For
this very same reason, CO2 tanks for gas-phase withdrawl MUST be kept 
upright - otherwise liquid CO2 will escape into the regulator with
highly undesireable results.
