A lot of the propane smokers are the same as electric smokers, many are just a dial for opening and closing the heat more or less
In saying that, there is one I have used that just has good solid builds and is really quite economical to buy also.
It will sit nicely around 200-250°F, if you want to get it down to 200ish, you can put the wood tray or another solid meat object directly over the burner, this seems the only way to get lower temps for smoking fish for instance.
In the pitmaster competitions, when they are allowed – many competitors actually use propane and win. The ‘charcoal’ is best, isn’t really the case.
These assemble together easily with a few basic tools and again, for the price you really can’t beat the results.
Plenty of space of all types of meaty goodness,
