I got one a few months ago, but havent had time to plumb it in yet.
Got a 11lb bottle, 50 jet, minimax, bottle heater, but forgot to get some spare time.
I havent figured out a way of explaining it to wife either yet.
I am so ashamed.
On a funnier note, I was reading a story the other day about a bloke who plumbed a bottle into his motorbike, but only had a tap on the bottle to regulate flow. I beleive it was the scariest few minutes of his life.
