beer gas express in elland do CO2, but you'll have to pay for one of their cylinders, when I got one from them years ago it was £40 + gas for the first one
must been 15 years ago that I started using them as I lost the contact details of the guy in Brighouse that did CO2
thanks for that bud ,,,have e mailed them see what prices are like ,,oh when a cylindar is in date is it stamped on the bottle or am i looking for some kind of sticker
