You should be able to just use a pancake regulator with most torches;
it's a cheap little doohickey and drops the pressure down to about what
you need, which is, depending on your torch, 5-10 PSI. A two-stage
regulator is going to be a very large and not entirely necessary
expense; most people do fine with single-stage regulators at half the
cost. Pancake regulators are a fraction of even that cost.

I'm mildly alarmed that Mr. Propane & Propane Accessories doesn't know
what a flashback arrestor is. :O! All it is, is essentially a backflow
valve that prevents anything (FIRE) from flowing backward into the tank
and causing an explosion.

You might want to check your Yellow Pages for a welding supply shop in
your area. Their torches are very similar and the way you set them up is
virtually identical, so they will probably be many times more helpful.
They'll have the right hoses, regulators, quick-connects, flashback
arrestors, the works.

I'm working with our local propane (and propane accessories guy to get a
100# propane tank for the studio. He has some regulators on hand and has
asked specifically what sort of PSI lampworking uses for the propane end of
the mix. Can someone help me with that? In the books or sites I've seen,
they talk about one-stage and two-stage regulators but they never mention
the PSI needs. He has the two-stage regulators, I believe.

Also, he thought that a flashback arrester was just sort of a gimmick. He
had actually never heard of the term and is going home at lunch to look at
the site where I first saw them to find out what they are. What's
everyone's opinion on this bit of info? Does he not know what he's talking
about, is the terminology just odd or are they a gimmick?

Thx,
