New or Used? Do you have a local spot to get your CO2 tank refilled or does your local provider swap empty tanks for full? If you have a vendor that refills tanks, that’s likely your best bet. In that case new or used tanks can make sense. If your vendor swaps out tanks, I recommend considering a good used CO2 tank. Don’t buy a new CO2 tank unless you’re certain that you have a good local source that will refill tanks. It doesn’t make any sense to buy a shiny new tank and then swap it out for a used tank right away.
Get a big CO2 tank. At my supplier, it costs around $20 to swap out an empty 5 lb tank. It costs around $25 to swap out an empty 20 lb tank. It’s more than 3 times the cost to refill the smaller tank! With the example prices, 20 lbs of CO2 would cost $80 with a 5 lb tank vs $25 for a 20 lb tank. That’s a $55 savings. I recommend getting as large of a CO2 tank as you can for your space. This will pay for itself in both in time and money.
