One less pricey alternative to Valoriani baby is a ZioCiro 80. A bit less expensive $4200 with gas/wood combo. It’s for sure lighter, but stilll refractory oven, probably better floor to bake with less conductive ( that’s what I heard at least) Valoriani looks more high end, higher quality, I haven’t used one myself , think the Valoriani is a great oven btw. There’s some nice reviews as well.
