Obsessed? Oh, no - you can't be. "Obsessives" are blocked a couple of steps before they can write about their collection(s) or hobbies in the Welcome Forum. Those of us who reach this place merely have our priorities in order. Welcome back, Mate!
Any particular torches you're looking for, especially US-made ones? I'll be at a swap meet tomorrow, and possibly at least one other day this weekend; safe bet that I WILL see blowtorches, but I don't know what's common or rare, what is realistic in terms of pricing, etc. Still, if something catches my eye and the price is low enough, I may pick up what I find.
