Really old post but...
I had mine filled at AirGas in Boston.. They have 2 locations around my area.. one by MIT on Vassar Street and another on the other end of Mass Ave.. 8 bucks gets you a swapped tank.
They are also very helpful if you say.. strip your regulator fittings while trying to change out the manifold and needle valve.. =X
