Thanks for the info, Sub. i appreciate it. It'll take me a while to understand the gibberish that Google Translator spits out when I check those links, though, since my Italian is basically non-existant.
I also found that the old G3Ferrari (Napoli) model is still available from Amazon under the brand 'Optima':http://www.amazon.de/Optima-Pizza-Express-Napoli-Ferrari/dp/B00BSX0JYU
I've read some reviews that the build quality for the Delizia (made in China as opposed to Italy for the Napoli) is really bad. Which model should I ultimately get?
Also - the second heat coil in the top: the way I understand it, both must be rated as 110V to ultimately be powered by 220V, is that correct?
As for taking out the thermostat, it looks like it's basically hot-wired, correct?!
I couldn't find any used Pizzamakers (apart from the one you linked to) at all, no matter what brand and whether broken or not, unfortunately. i would just buy a used one instead and try to fix if I could find one :/
I was able to find an original (?) but used red G3Ferrari Pizza Express Napoli (not Delizia). It has two knobs on the top of the oven - is this the original "good" model? I can buy it cheap but must drive a long way for it. Can you please outline the minimum mods I should do (I believe you called it M1) and what type of second heating element I would need for this oven (110 or 220V)?
Also, the pizza stone is very dirty on the used one. Can I just flip it over since I don't know what the previous owner did with it?
