I have owned this model and its ancestors for 20 years. The older models were attractive because they offered Charcoal grilling but Gas Ignition. I went through 3 different versions over the years and loved them all ,but the older models required a special small propane tank that was hard to fill.( I bought 2 extras) This latest model incorporates many improvements including an improved charcoal bin and easier ignition system and throwaway gas supply. LOVE IT !!!
