Of course I had to buy what was available in Italy. I did no shopping here in the US. I know that it is stainless and considered second rate by the purists. I am not a brick layer and me building my own oven, on my vacation of only 14 days, was not an option. To buy the correct refractory bricks, cement blocks for the stand, 2 layers of insulation, pay for the labor of a maestro bricklayer, the correct cement, all of the other parts was actually more expensive than the Alfa when I had estimates given to me.
I did see other SS ovens and in comparison, this thing is really built! It weighs in at 330 pounds and will do 4 pizza at a time. There is some mass. It was still warm hours after I made that pizza in the picture. It was worth the extra money to get something this substantial especially in lieu of a real brick oven. I really doubt that someone could build one like this one at home with the steel in their back yard. It is made from very thick stainless and does not come off as a toy in person. The floor is made from their famous refractory bricks. Alfa has been building ovens for along time and has a great reputation. They make a little one called the "Ciao" and that one is toy-like and is in 800 Euro price range. Obviously, the 4-pizza model has more to it.
Not all SS ovens are built the same.
Knowing that I can just heat and cook great pizza without a lot of time heating and I can move it around or take with me when I move makes it worthwhile.
