I currently have, and have had a Smokey Mountain propane smoker for better than 15 years. While it has served me well, it is getting old, and I'm getting tired of constantly having to adjust the gas flow to keep the temperature somewhat stationary. I have been reading about the Masterbuilt electric smokers and they appear impressive. I do have some questions before I act: 1. I see the MES 40 is on sale at a few locations. I also notice that it is a "discontinued model" Is this something to be concerned about? 2. I'm assuming (again) that this smoker, being digitally controlled, will eliminate the varying smoking temperature problem? 3. I do a lot of sausage smoking and it is necessary to remove the racks to hang the sausage. I realize this is probably a stupid question, but again I assume this in not a problem (to put wooden dowels in the rack holders. 4. I guess I have more reading to do as I see the "A-MAZE-N-TUBE" is recommended for this smoker. Thanks in advance for any suggestions, advice, warnings, whatever!
