I did a lot of research on Kamado grills before making the decision on Kamado Joe and more specifically the BIG JOE! I have not been disappointed. I love the many options for add-ones you can get.  The cooking space is amazing what you can fit on the standard grill surface. The flexible level cooking with the deflector plates makes great searing side and a deflected roasting area. 
I could keep going about why I love the Big Joe, it has make a great addition to the backyard.
