Re: [APD] re: complete CO2 system -- Don't give up the Ship-ping


Using a tank-swap CO2 supplier which insists on using only
it's own tanks;

Using a tank-swap CO2 supplier that will use any properly
(according to the DOT regs) tested and stamped tank.

Using a CO2 supplier that will refill your own tank.

Buy a tank locally or from an on-line vendor.

We've heard from folks from several places around the US.
Seems pretty clear that options vary from one place to
another. You might be able to keep using a tank of your own
but not care whether you do or not. Buying a tank on-line
might or might not be cheaper. CO2 tanks cannot be shipped
filled so you have to figure in the cost of a fill when
comparing prices to local tank sources. It makes sense to
investigate your options before you buy.

And it's worth iterating, most of the cost of a fill is for
getting a fill at all, not for the amount of CO2 -- larger
tank refills can be much more economical than samller tank
