Barb, that one you have is the new and improved model.
They added an electric element to fully cook the loaf on the top section.
We have one that I baked only 7 times in it. Only problem, is it is the previous model before the improved one.
What gets me, is they flat outright admit that the older model did not bake the top section of bread; then by introducing the new and improved one that is currently their machine.
