Wallas makes an assortment. Very expensive but apparently work
as advertised. A friend of ours lost
the top plate in a minor accident
and it was very dear to replace with no after-market suppliers, etc..
He ended up paying more for a new top plate than we did for a who new LPG cooker.
So, the price
is the minus, otherwise all good things I have seen and heard.
Probably the choice for ones who sit or sail in places far from LPG taps.
