the best thing to do is support your LDS I would like to see you get your tank filled on ebay or at scuba.com or liesure pro. Air& nitrox is the one thing that you have got to have to dive you may think that your filling the pockets of the shop owner buy paying a higher price but unless you have been there you don't really know the profit margin I payed $20,000.00 for my Air compressor to maintain do the air tests buy the 02 change the filters and pay the electric @ $5.00 air & $12.00 nitrox I will never break even on the cost of the compressor never be paid for the labor and with out it I really have no shop classes dont keep the doors open only retail sales do. Hey what do I know I only live it every day and I dont know any rich dive shop owners if you do they won"t be that way long
