[PSUBS-MAILIST] Fw: used 80cf scuba tanks

[Tom J Whent via Personal_Submersibles]

If you do buy them, another important aspect for you to check is the alloy
of the cylinder. I can't recall what year Luxfer stopped manufacturing them,
but any which are made from  6351-T6 aluminum alloy are prone to stress
failures in the neck/thread area. I don't think a reputable shop would sell
them, but it is certainly worth investigating. The failure of these tanks
can be catastrophic. The alloy will be marked on the cylinder.

Seems high to me for something manufactured in 89.  I'd ask for a new hydro
so it's good for five years.  Lowest new price in US seems to be divers
direct at $180, but if I were you I'd check out craigslist or similar online
advertising where you will probably find a better price.
