There's no question that bulk is way cheaper than 1# disposables. Around here they sell 2-packs of fat boys for five bucks and change, but bulk is obviously still cheaper. IMO, either way the gas bill is relatively small, at least with a HH type torch, and especially compared to fancy glass and nice tools.
I also give a big hats off to Dale for all the info here- I changed a variety of things in my setup based on what he's written here. He's also certainly right in that everybody has to decide on the level of risk they're willing to tolerate. As I said in another post, I'm not willing to stop doing everything I like (almost all of which is dangerous) for the sake of reducing my risk to zero. I also don't have the money to "take every possible precaution" which, if you think about it, is physically impossible anyway.
I've made it this many years without major incident by having a very sensitive mental alarm system that says, "Hey, wait, STOP! What could possibly go wrong here and how can you assure that it doesn't?" I'm also well aware that I can't think of everything, get tired, get lazy, get stupid and things can go wrong in spite of my best efforts. This high pressure thing set off my alarm. It's outside the envelope I feel comfortable with. IMO, if people still decide to do it, they should use top notch components and follow a strict inspection schedule.
