My ideal is the same as Rapaire's, ie. a gas hob and an (idealy fan assisted) electric oven - I had that setup once when I had a flat in Llandudno and have not yet managed to re-ajust to slow electric tops. I can't claim to have used one of the newer type of electric tops which are supposed to be more responsive than older electric rings but everyone I know who has gone down that route has had reliability and cleaning problems - it seems with some you have to take great care with the surface.
