After much research I bought the Kamado Joe Classic I for my son.  His review to me was he 1st cooked a pork roast just to season the grill. Next he cooked a spatchcock turkey for his in-laws. He sent pictures and it looked really good. a 13 lb turkey for 6 people. Not many left overs.  He is really excited about learning more and grilling (and smoking) on the grill.  I see some additional accessories in the future.
