One should also get a regulator ($50-$100). The 2000 PSI raw gas pressure
can be very dangerous to "play" with without one. Also, larger tanks will
need to be delivered and mounted according to local laws. The gas supplier
can fill one in on the details. High pressure gas tanks need to be handled
carefully! Very small cylinders are available too. Check around.
Apparently, helium is available in small cans for filling balloons for
parties and such. These are simple ~5 ft^3 aerosol cans that are available
at places where party supplies are sold. I haven't found them yet in my
area but they are supposed to be out there.
