This is a deal, If you baught new, one tank would be over $200.00. If you buy used, then you would have to get the tank Hydro'd and visually inspected, then filled. If the valve needs a new burst disc or repairs, this could cost over $40.00 or more per tank. $110.00 may sound like allot of money, but not after it is all ready to dive. I have 2 excellant aluminum 80 cuft tanks that were built in 1993, the current hydro is 7/08 which expires 7/13. The tanks are PSI inspected as of 6/09 which will expire 6/10. Both are full ready to go with boots and caps. The valves have been cleaned and inspected. Im selling them at $110.00 each or $200.00 for both.
