I have had my own oxy/acetyline tanks for years, so it was a no brainer for me to wish to buy my CO2 and Argon tanks. I just run them back an exchange them when they are empty. No waiting, which was always a hassle for the larger tanks I had. I don't have to pay for inspections, and no demurrage, which I always found to be a real expensive proposition because I am a home hobbiest and I can sometimes go for a spell without using the tanks.
It is a personal choice, that is why I explained my reasoning.
