If you go with propane, buy your tank. Don't lease it. A leased tank can only be filled by the company you're leasing it from, and they typically charge a hefty premium to fill a leased tank. Kind of like a cell phone. Owning your tank gives you the option of shopping the marketplace for the lowest price.
True but you also have to buy the necessary pressure regulators and if the tank leaks it is your dime.
Be sure you live your life, because you are a long time dead.-Scottish Proverb
