I have just had my CO2 tank refilled for the first time since I
bought it over a year ago. I estimate I have "lifted" about 20
cornelius kegs of (sugar) primed beer with the 5 lb or so of CO2 that
originally came with the tank.

Although I remember reading somewhere that one should refill the tank
before it is totally empty, I didn't have the chance. I used it
one evening till it was totally empty with no ill effect to tank, keg
or brew.

Incidentally, refilling it to 800 psi cost be $12.50. I now have a T
connector with two valves, so I can dispense two different brews
