I went from an offset firebox smoker to a Masterbuilt XL propane smoker last year. I was looking for something that I didn't need to baby sit. The XL does a good job but I still have to watch the temperature pretty close especially on a hot day. I am afraid to use it for an overnight smoke. It seems the older I get the more lazy I get. I have been reading a lot about electric smokers on this site. It seems most owners like the units and use them for overnight smokes so I would like to try one. Have been looking at the MES 30 & 40. Which one do I want and where is the best place to look fro a reasonable price? I am used to a large smoker with the XL I now have, but I never fill it up. This is a great web site and I appreciate everyone's help.
