I have 2 30" Masterbuilt smokers, the 2nd one is yet to be used. Smoke has always been a problem. I converted to a Smoke Pistol smoke generator and wasted more cartridges trying to get them lit than one that I used. I obtained and installed a Smokin-It cold smoke generator smoke problem solved! I also have a Masterbuilt propane fired one, both temp control and smoke are problems. An inexpensive unit that is tall enough to hang 20" casing would be ideal. If I was not in my mid 80’s I would design and build one,
