I spent today performing my every-two-years maintenance on my gas BBQ. It's a three burner "Turbo" model made by Barbeques Galore. Back in 1991 when I bought it, Barbeques Galore's models were all made in Australia to fine quality specifications. The burners are cast metal with holes drilled for the gas to come out and burn - much better control of the flames that way. The grills are cast iron. The cart is jarra wood, some extreme hardwood version of eucalyptus they have in Oz. The metal hood is porcelain black coated. They give a 5 year unconditional warranty.
