fantastic - anyone else opinions please !

i think the general concensus is that argoshield is better but its a pain to get hold of unless you have a friend in the trade - I am in the trade myself but dont have anyone who would get me a small bottle for home use you see

anyone else?

and another question - how long do you find the £10 bottles of CO2 last that you get from B&Q? I know you can get pub cylinders or whatever, and sometimes you can use pretty much any gas bottle as long as its safe and clearly marked with whats in it - what i hear anyways
