How is your brew rig powered?

Thats ridiculous man! I get at least 9 brews from my 9kg LPG bottle. I have to bring 72L wort to the boil, but not my HLT (elec)
I get my bottle refilled in Sydney for approx $16, so its less than $2 gas each brew.

Birrong hardware store?
Those guys are great, i used to travel from the north shore there with 3-4 gas bottles. Including petrol its way cheaper than swap n go (it was about $35-40)
I only swap n go to get a new cylinder thats in date, make shure you dig to the back of the rack for the mest date).
