I will not argue with George Irvine who happens to know what
he   is   talking   about.   However,   in  Europe,  we  get
contradictory  information  on the tanks issue (Al vs steel,
etc.):

(1).  It  is  considered that steel tanks (chrome-molybdenum
steel) are safer, last longer and require less weights;

(2).  Aluminum  tanks are not widely available in Europe ...
they  never  hit this market and, as far as I know, they are
not produced in the union, are they ?

If  they  really weigh 1/5th of a steel tank and cost 1/3rd,
being  EQUALLY  safe  (are they ?) I would certainly welcome
them ...

But,  again,  if  they  are so much better for ocean diving,
light  and  much  cheaper:  why didnt they ever hit the euro
market ? Could any one explain this ?

Or ... are we being fooled by the "market-forces" in Europe,
too  ?  As far as I know (hehe, no flame intended), we still
have a less of a circus in the euro market ... dont we ?

cheers,
