Today I went to get a hambleton bard gas refill, and found my usual place has stopped doing them, I have three King kegs and couple of week ago decided to brew beer again after a break of a few yr, do any of you lads know what I need, to gas these kegs now without three days camel ride to another home brew shop,to get a refil, as all the places, that's been suggested no longer do them, I know I can send away for a refill but what a ball ache, I am looking for a sensible solution, at a reasonable cost,
