Thanks, Ernie, for the reply. I am cool with that. I checked at the
local AirGas place today and they'll sell me that CST 280 for 1,700
and change. I'm excited about that. I have someone already biting on
the line for one smoker and should have an answer in a day (and a down
payment)...then it'll be time to buy a new toy (plus the TIG
attachments).
Thanks again for this info and the info on the thiols (with that info
and what Gunner pointed out I think I can reconsider my ban on the use
of used propane tanks).
