Thanks for the comments. I once approached pressurized CO2 with trepidation (after all, it's pressurized gas, it could explode, right? All kidding aside, it won't if you use it properly ), but after having done the research and gone through all the hoops, it's much simpler now.
Great writeup! Very informative and very detailed.
Although extremely rare, i do think you should include the possible dangers associated with pressurized tanks. In early January, i was on my way home from the LFS with my first co2 cylinder, and it randomly (didn't bump it or anything) depressurized in the car as we were getting off the highway- leaving me with a very severe second degree burn on my right leg. I now have a pretty nasty scar that is a little bigger than 3"x3". We're still unsure of what caused it to depressurize.
While the chances of this happening are literally 1/10000+, i think it's important for people to know that these can be dangerous things to have in your home. Take all pre-caucions necessary to be safe.
Would i go back and get another cylinder? Probably, although now i'm a little frightened by them. I'd definitely keep it under a thick stainless steal box, LOL. Understandably, my parents don't like the idea of getting another (when they didn't even like the idea in the first place).
