In my mind, better heat retention equates to less air needed for combustion resulting in food that is more moist and tender. I like my egg a lot but am not married to the idea that it is the only good option for grilling. It cooks very well. Unless I break it, I shouldn't have buy anything else again. For me, it's a reasonable investment...even better if it's second hand and priced accordingly.

My cast iron gas grill is on it's third set of burners and I can't see putting in a fourth.
