Most welding supplies also carry the the fittings
needed to change standard regulators over to the
smaller cylinders. A 10 Cu Ft Oxygen tank will last
real quick, especially doing any cutting. You might
consider at least a B tank of Acetylene and about a 
70 Cu Ft Oxygen Cylinder. They are still easily
transportable and don't cost much more than the
smaller cylinders. It also cost just about as much
to refill a small cylinder as it does a larger one,
another factor to consider. For soldering you might
do with an air acetylene torch you might consider
a Bernz-O-Matic type torch with MAP gas. It burns 
almost as hot and is quite a bit safer. When using
acetylene, under no circumstances, operate the 
acetylene line above 15 PSI. If you do, you will
be asking for some serious trouble. Under those
conditions, Acetylene can explode by it self without
the presence of air or oxygen. I know of at least
one person who accidently killed him self in this
manner.
