Yep you're right, Jimmy Reiser out of Rimbey,AB makes them and I can say they're real handy. Oxygen Products here in Edm. sells them and quite possibly Arrow welding. Both have sites and you can toll free them a call. I drove down to his place to buy mine and paid $125 and that was about 3-4 years ago, so I don't know what the current price is. Bob
