True, the manufacturing is probably a little tricky. I'm still curious what their profit margin is on this. The guys making their own DIY of the Bonfire size have to put in a lot of labor, more labor that I'd put in to save $200. But if you want to DIY one for minimal labor, and a low price, wait for the end of year clearance on the Akorn Kamado grills (goes for $87 at Walmart). It's already double wall insulated. Drill our the rivets, take apart the two shells, pull out the insulation, drill the holes in the inner and outer shell, put back together, and there you go!
