The BOC ones we use have 300 bar and at 118quid , can't complain we use two bottles for titanium , the air liquide seems to come 200-220 bar and some of the back street suppliers is only 100 bar so whilst a larger bottle may seem to have more gas if it's only 100bar in it then ....
BOC distro in London is shite it seems so went to air products, 300 bar, 80 quid a pop (plus 40 for delivery) and three deliveries a week for anyone looking in the smoke.
