This makes sense. What little savings I ended up with was outweighed by the risk of a tank failing hydro, my time driving to hydro, down time for hydro etc... Seems like I can buy a new AL80 from Divers Supply in Jacksonville, FL for $155 nitrox ready with VIP.
If you like using AL80's..... up here they suck.... (77.4 cu-ft & horrible buoyancy characteristics)
YMMV
