Anybody have this grill? I think I'm treating myself this Father's Day, and I wanted to know anybody's personal experience with it. I've coveted it for a while now, and seen it up close many times. I think they slightly changed it from last year to this year. And I'm not even one of those Neanderthal-type, stereotypical "I-don't-know-how-to-anything-with-food-except-grill-it" meatheads. I just love charcoal, love William-Sonoma products, and love this grill. It seems to be very well-made, and I really love the cast iron grates. Anybody have it? Pro's, con's? Do you have to season the grates before using? Worth the cash?
