I don't know where you live OP, but if you have a used restaurant equipment place you can buy CO2 tanks cheap. I have 2 ten lb tanks I paid $25 each. Swap them out at airgas or haun welding supply @$18 per for full ones. There's no need to buy new because these guys will only give you recently tested safe tanks. True they aren't brand new shiny aluminum but who sees them besides you?
