Or you can get 5, 10, or 20 pound DOT certified CO2 tank and an adapter (https://a.co/d/07ISNVqA) so you can refill the small tanks and keep the big tank somewhere tucked away so you don’t have to worry about the hose for connection. Check home brew shops for beverage grade CO2 refills I found my local home brew shop would refill a 5 pound tank for $25 cheaper than air gas (a specialty store I kept seeing mentioned online for CO2 refills) I also heard that connecting the large tanks allows for issues with too much pressure causing wear and tear on the machine. Unsure if that’s true but I don’t want to drill a hole in my counter so didn’t bother researching it much since refilling the small tanks seems to be the right choice for me anyway
