Diveusa has a better price. I paid the same price and it came with a tank boot and cover. You can omit the cover and boot for less cost. SHERWOOD 80 CU. FT. ALUMINUM SCUBA TANK
You can check the dive shop for a used tank, the one I get my tank filled at has freshly hydroed, used tanks for $80.
Too bad you're in WestLA. AA paintball in baldwin park fills hpa and co2 for a $1.
EDIT: Wasn't there an I&I in west la on the corner on sepulveda and national?
