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.
You obviously have no respect for skilled craftsmen with statements like that. Do you have any concept of what a trained, skilled sheetmetal worker makes in this day and age? I can assure you there isn't a product around at retail that is made by one due to the labor costs. Your overpriced oven was built by unskilled production workers with minimal on the job training, I will guarantee that. I could build it in my backyard standing on my head. As for materials, I have a pile of 16 gauge stainless enough to build 5 of them, and I would bet there isn't a piece of 16 gauge on there, probably 18 and 20.
My issues with ovens like these have little to do with tradition, heck I stated the blackstone as an alternative, and every thing to do with their inflated pricing and complete lack of understanding of how a wood fired oven works. Do you know why every masonry wood fired oven around has a dome thicker then the floor? Because heat rises. The top of the oven will always get more heat then the bottom. The dome and it's extra mass serves as a heat "battery". It stores the heat that helps keep the temperatures inside the oven stable and recharges the floor. Your oven has no battery. The floor has thermal mass, but once you place food on it and start removing heat from it you are left with only the fire to recharge the floor. Temperature stability will be a major issue, as will extended cooking sessions like pizza parties. Even then some may deal with the short comings and inflated price if there where no alternatives on the market or it could produce a 60 second neapolitan pizza. As already mentioned the blackstone is on the market for $370 and can do a 60 second pizza pretty easily. Your 100 second pizza looks good, we'd all eat it, but when trying to sell people on an oven 100 seconds won't impress anyone, especially not an oven that costs up to $4k.
The issue here isn't with you, your oven or your pizza. It is with trying to sell OTHER PEOPLE on this product. It simply isn't a purchase an informed consumer should make.
