Yep.
G&G sell a pre made herms, also the braumeisterr which is a single vessel rims. I dont know if they usually sell them, but i have seen in G&G a Sabco Brewmagic, which is a three vessel rims. I,m sure they could organise the import of a More Beer system too.
And Beer Belly makes and sells Rims/Herms systems in various specifications.
Other HB shops might sell their "own" systems, and i imagine that there would be at least a few also selling Braumeister, Sabco and perhaps even More Beer rims/herms systems.
Be prepared for a bit of a wallet shock though.... You wont be getting any change out of 4 grand for even the cheapest
of them.
