All gas cylinders undego periodic testing for safety, usually once every ten 
years.  With the number of cylinders out there, that's a lot of cylinders coming
up each year.  Some percentage must fail.  The testing is done hydrostatically, 
which means the cylinder is emptied of gas and filled with water.  You can't get
too much safer than that!  Why not seek out the failures and use them, if you 
must, as a metal source (for bells or whatever).  But remember that you STILL 
don't know what's in them.  There still could be flammables inside, so treat 
them accordingly.  Maybe refill them with water and cut them with a hacksaw or 
an abrasive wheel that can tolerate striking water(?).

I got a couple of these cylinders from my welding suplier onse. Don't wory
about having to do the cutting yourself. They destroy them, as gas cylinders,
by cutting the bottoms off using what looks like a giant can opener. They do this 
while the cylinder if full of water.

I got mine for free but I supose that scrap cost would be about right price.

Since the bottoms are off there is little danger of catastrophic explosions even
if you weld on them. The open end is the secret.
