Fully recommend the Aussie built (apparently) Broadwater marine stove. I'm very impressed in the quality and build.
The Kiwi built "Mariner" stoves are equally as good as the Broadwater if not better.
The all stainless construction of both of them is where their value lies.
If there are problems with the burners a competent gas fitter would be able to refit the stove with a complete new system of burners and controllers including piezzo igniters and failsafe burners.
