We bought a gas cooker from Dolores in Tortosa which is found at the top of the pedestrian area and turn left.  No delivery charge to Alfara either.  Only problem is that the oven does not have a regulo which makes it difficult to gauge the neat for baking and I am not very fond of burnt seed cake.
We did bring a cooker over from the UK but could only obtain jets for the hob which meant that the oven and grill got very hot.
