Dang it Dan,I also have an Ooni, and I like it a lot. I bought the add on gas burner for cold weather use and its great. Light it, set a timer for pre-heat and then cook.
Two benefits of a dedicated pizza oven are they can get A LOT hotter, and they use much less fuel.
The gas attachment for the Ooni is rated at 15.3K BTU and will easily get to 850F stone temps.
My E330 burns 48K BTU and takes a long time to get the stone to 700F.
This discussion is getting me hungry. I think it's time to make some pies !
Now I will have to go buy the gas adapter and convert my Ooni Frya.
