Hi all I was wondering if anyone here used the Dennerle re-fillable Co2 canisters (the classic line range)? I read somewhere that the bottles are only refillable by dennerle stockists? I can't see how that would be, but it does mean that I won't be able to go with a dennerle kit if it is the case. My LFS does Co2 refills - he sends them to someone else, they refill it, and then send it back to him. Thanks!
