Yep I do, I don't have any though [] as the Aussie one's start at about $800 to $1000 and go up from there and that's IF you can find one for sale. I may have to go and have a dig somewhere that they can be found [] (no company's used them in Victoria as far as I'm aware, there is a few from NSW though).
Yeh, I would love to dig one, but like Irish, I'm in Victoria so no chance. West Oz would be the go, they have about 12 different ones including one with a blue top and another with a valve patent.
