I use a small oxy/acetylene torch set up /w the 'B' size tanks.
They are the smaller tanks, about 30" tall so they don't take up the entire shop.
The Acetylene tank holds 40 cu/ft,,the Oxy tank holds 60 cu/ft IIRC (Though I think there's a slightly smaller version that holds 40 cu/ft also)
Anyway,,right now a re-fill for the 'B' size acetylene is $28.50
Refill for the 'B' 60 cu/ft Oxygen is $16.50
Mapp gas is available the same way acetylene is in refillable tanks of different sizes at most places that sell welding supply and gases.
Even Propane can be used as the fuel and do alot for you and that can be very inexpensive.
I suspect the small store bought disposable Mapp gas and Oxygen cylinders are costly compared to that.
You have to figure the cost of either renting the tanks,,or buying yours into the mix.
But it may be worth doing it that way if you do any amount of work with the torch.
One shop I worked at was on Propane for it's heat and hot water.
So the bench torch simply used the same propane source and a small oxygen tank.
It was hot enough to do some small welding,,I managed to melt a couple of small ejector parts all by myself.
Just some thoughts..
