the egg is the most awesome thing in the entire world imo. but i really wanted to learn how to smoke stuff, that's why i got it. if you're not interested in getting into that then i would just stick with what you have. you can use the egg to smoke or grill, with temps from 150 to 1000. i've grilled pizza, steak, and lamb on it. i've smoked pork shoulder (pulled pork), brisket, chicken, fish- salmon and halibut, jalapeno poppers, back ribs, spare ribs...ohhh I smoked my thanksgiving turkey on it, and i've smoked a few beef tenderloins, and some racks of lamb. i'm sure i'm forgetting something but those are all in my regular rotation. i got mine last winter and smoked all last spring/summer/fall, just about every weekend. this season I've had it up smoking 4 times or so.
like i said, i wouldn't buy it just to use for grilling, it's real strength is it's use as a smoker. to me, a grill is a grill is a grill.
