I just completed the conversion of my unit to a reverse flow (was a single pass). Test fire and cook last weekend. MUCH happier with the overall temperature distribution across the full length of the grate. It's about 20 degrees end-to-end. Now that I seem to have my arms around that, I want to move to the next level and better control the temperature over time. Of course that takes me to a STOKER unit....if I want to pay that much. I know there are others, but the Stoker seems to float to the top as fas as dependability, accuracy and flexability. I am asking for your opinions and experience regarding a homemade version versus the purchase of a Stoker? It's easy to get a PID temp controller, cheap power supplies, fans, thermocouples, etc on the internet. I am plenty handy with all the electronics and wiring. Making one adds up to less than the cost of a Stoker. PLUS you get the satisfactions of saying "I built it myself" when others see it. Please chime in and tell me your thoughts!!
