I have no idea what they cost. I built mine years and years ago out of scrap pipe from different jobs I was on. It started out as just a 4 ft pipe and some plate. Over the years I kept adding to it. It's been like this for about 30 years.The machine that is a reverse flow is unlike yours. It is a purely horizontal pit where where various ideas in design attempt to moderate and even out the physics of a hot firebox on one side against no firebox on the other. In your case, heat moves on into the vertical chamber, which become a heat source or massive heat sink itself and moderates heat loss from one side of your horizontal chamber to the other side. Those rigs are a couple grand are they not?
