Since you are still having issues, have you considered going with a kettle and a temperature controller? I considered going with a 26-in kettle and putting an aftermarket controller on it. That would have had me around the $550-600 mark... A lot of surface area and stable temperature.
I decided against that because I do like the efficiency of kamados because in the long run I'd be spending too much money on fuel if I went with that 26-in kettle.
so I picked up a summit kamado E6. There is very little that can break on it. That's what's great about kettles and kamados. If anyond needed more space, they can always put a 22-in stainless steel grid on top of the existing grid for an extra 380 sq. Inch (830 square inches total then).
I know you're attached to the smokefire

. Based on my short stay at the traeger forum, they have their issues too. But not as bad as what you're having. The pro series and below have more issues than the ironwood and the timberline.
Anyway, I know you got it for a steal of 800 and some change. Reminds me of George Costanza from the Seinfeld episode. He parked in a space right outside his building, which is prime real estate. But then he refused to move his car cuz he didn't want to give up his spot
Don't be a Costanza. Don't keep it just cuz it was a great deal. Go to slickdeals.net and believe me you're going to find other deals out there. I visited that place almost daily but I have plenty of alert set up
