Ready to pull the trigger. My obsessive-compusive research has yeilded no other answer than ceramic charcoal cookers are the way to go. Some questions remain and I could use some help:[p]1. It would appear that Viking has largely ripped off the BGE with their stainless steel version of the ceramic cooker. Other than good looks is there any advantage to this set-up (ie: is the Egg exterior fragile). Could buy two eggs for the price of the Viking.[p]2. Are there accessories for the XL BGE? I would like a larger pizza stone (18" or more), Larger plate setter, etc.[p]3. What would be considered the average lifespan of the BGE when placed continuously outside through wide swings of temperature (10 deg to 100 deg F and up to 100% humidity).[p]Thanks.
