I've been seriously thinking about getting a larger bottle. Having to
get it refilled every month is too much of a pain. It's not really the

refill), but the worry of having to check all the time if it's empty.
I only have a low pressure gauge, not one on the bottle pressure side.
Maybe I can trade my small one in for a larger one or get another used
