So an internet acquaintance of mine found 15 of them in the back of a truck in a junkyard. He happens to be in Australia. He's been messing around with them and for all but one which is a bit "whimpy" as he described it they all apparently work. I ran a quick shipping estimate and it's looking like it will cost about 100-110 Australian to ship them over. I want them, but damn! That's a lot for shipping. Anyone have any ideas? Is it worth it to spend that much on tubes like that?
