I've been using NG for... hmmm, at least 15 years with no problems. A
simple set-up with one torch. No pressure regulator or booster
needed, and the connection is through a hand valve to the NG line
that feeds the water heater and furnace.
With standard safety precautions (close the hand valve when done for
the session), NG is the 3Cs: clean, convenient, and cheap. Be
confident; talk to your local welding supplier (who will be your
source of compressed oxygen); it's not rocket surgery. Judy in
