I'm after 4 x 9L kegs. Not fussed if they are pin or ball lock (preferably all the same though). I live in Newy but am happy to travel to the greater Hunter and regularly visit Sydney's North Shore.
MHB has kegs for sale. Not sure on the price but think they had gone up a little since I bought them last. Give him a call or email and he will be able to help you out.
