Torches

[jsheds@ix.netcom.com (Jim Shedlauskas)]

Have any of you used one of these portable acetylene torch sets?  They 
typically have a 10CF Acetylene and 20CF Oxygen cylinder.  They sell 
for around $250 to $300.  I was wondering how long I could go on a gas 
fill with a set like this, using it occasionally to heat something or 
cut off a bolt, a little brazing, etc.  They look kind of handy, and 
there's no hassle (yet) getting the gas botles filled.  I'd appreciate 
any info you can share.
