I have an electric Masterbuilt that has a probe and automatic time and temperature control that function well. The only thing I am not happy about is that at lower temperatures (180*) the heating element does not seem to make the wood chips smolder and produce smoke. As a result I tend to use it more as an oven/dehydrator than as a smoker.
If I were buying one again, I think I'd look for a gas/propane operated one because it would have a flame that would be better at making smoke, I think.
If anybody has a suggestion about how to make this work better for me I am all ears. Thanks!
