Hi again all. Just an update. I got my orca/EZ Torch and it's excellent. I decided to go with the 3.9 refillable propane canister from flogas. It's a bit scary having it in the house -top floor in my attic room workshop. But I'm following all the safety advice after use etc and got a new fire extinguisher.

But I'm so glad I got it. Thanks for all your comment on this. It really helped.
