Tesco are now stocking Old Speckled Hen in reusable easy kegs....
I know they used to use an integrated CO2 cartridge which made them difficult to reuse but the one I've just bought is in a standard Easy Keg....£16...
Pretty easy.... The bung on the top can be removed by pulling the vent plug out, drifting the red plug in to the keg and the removing the main rubber bung body by wrapping dental floss round it and wrapping round a screwdriver and pulling. The guy in the video linked below uses pliers but there is a risk of damage...
I got some of the old ones and found that they were no good as not enough pressure in them. My mate who gave me them has told me there the other ones now so looking at getting some empties of him.
