The CO2 bottle is certified for 10 years if new..
My local homebrew shop also does swap bottle.I take my empty one in and swap for a full one just like the BBQ gas bottles.
So I may actually never have to worry about certification again.
I also dont think its that expensive to do,about $50 from what a mate told me a couple of years back.
Hope that little bit of info helps.

ps I did hire from BOC and the 12 months i did, rental went up $2 a month.They make money from refills not hiring so would prefer to hire to a HEAVY user than a casual user.I got about 12 months from a 6kg bottle.My bought bottle is 6.8 like the above mentioned one.

how much does the paintball tank hold?
i had thought of them, but figured they'd need filling all the time.
Got the size of the 6.8kg tank:
690mm high
180mm wide max

They hold about 20oz, I use it on a small tank (40L) and it lasts ages.

i had considered using one of my scuba tanks. They cost me $300 new and hold 12litres and handle 232atm of pressure. I looked up a conversion for CO2 and 1 litre of CO2 liquid (under tank pressure) weighs close to 1kg, so thats a 12kg tank for $300. But i highly doubt anyone would fill it - plus the conection is completely different...
I was considering a fire extinguisher, but i'm thinking i'd rather spend a bit more and do it right...

CO2 has no liquid state its one of a few elements that goes straight from a solid gas state and vise versa.so there would be a different pressure factor when say compared to O2 or natural gas.
like its already been said do it properly and safely

CO2 has no liquid state
this is true at normal pressure (hence the name 'dry ice') but i dont believe this is true when compressing it, it will become a liquid.
Have a look at this conversion site:

increasing pressure only changes the temp a change of phase will occur at. with water in a pressure cooker,increase in pressure causes an increase in boiling point.

well i got my regulator now, and will be picking up my co2 tank on friday.
i must say that the fella's at u-brew-it are most helpfull.
they ordered in the tank and got it delivered to my local store to make it easier for me to pick it up.
Anyone looking for a co2 tank, send an email to Tim at the midvale store (ubrewit@amnet.net.au) and i'm sure he can look after you like he did for me.
