I put it off, and put it off for so long, for the same reason. But, at the beginning of the pandemic I purchased one because getting to the store for water became more than a matter of gas and time.
In order to keep my conscience clear, we bought an adapter off ebay and a restaurant grade CO2 tank. I refill my own gas bottles. It’s also tremendously cheaper this way, because the local airgas or whatever refills that big tank for about $20.
The moral calculus is complicated, no lie. I don’t feel great about giving them money, but I feel better about it only having been the up front cost, not every 6 weeks.
