what size tanks? i assume at least 20 CF tanks, and at that price, it's almost a steal (if they are still in test, if not, that would be another 60 dollars tacked on).
find your nearest airgas, and ask if they are willing to trade tanks. tell them what tank you have, and what you are looking for.
i recently did an exchange of a 5# aluminum co2 tank for a 20 CF steel oxygen tank, as an even trade, so i just paid for the fill of the oxygen.
