I have the Classic De-Luxe 110cm duel fuel for about 3 years now, and like
huskerdu I too have had no problems. They are expensive but I think as modern cookers go they are quite well built.
When you say 'dual fuel' do you mean solid fuel and oil/gas or electric etc? They are very expensive if you go for condensing models, also the burners on the oil fired ones are not the best burners on the market.
