It is time to graduate to the "next level" smoker. I have had a vertical propane smoker and now have a ME S40. I use them for smoking quite large amounts of homemade sausage I make a couple times a year and weekend goodies. I also do some competitions in my area. I am looking at a vertical insulated box style smoker. I am interested in the 3 I have linked below. http://pitmaker.com/product/vin/?vin=62369936 http://www.backwoods-smoker.com/our-cookers/g2-party/ http://stumpssmokers.com/Products/Gravity-Feed-Smokers/Vertical-Smokers/The-XL-Baby I would appreciate any advice or experience anyone has with these cookers. I would also be interested in any other candidates you may have.
