The Koda is a very hot oven right now (no pun intended). I know at least 20 people who have pulled the trigger.
With these types of ovens, early adoption is generally not a good idea- and it's an especially poor idea with a company like Ooni, who, for years, until they got their act together, were selling what were basically door stops to unsuspecting beta testers. They eventually got it right with the Ooni 3, but versions 1 and 2 should never have been sold to the public.
I'm not necessarily saying that the Koda is half baked, but until it's in the hands of someone who knows how to make pizza, and we can clearly see what it's capable of dong, my advice would be to wait. With these types of ovens, there's usually longevity concerns, but Ooni, so far, hasn't had problems with that.
Normally it takes about a year before we know how well an oven truly performs, but, there's so much interest here, we might see results as quickly as 6 months.
For those interested, here's further information on the leading sub $1k outdoor pizza ovens, along with a spreadsheet containing their perspective specs.
