I have the 470 in black enamel. LOVE IT!
YES, it's a lot of grill! YES it gets hot as hell! But one of the great things about the grill is you don't always have to use it as a flame thrower! I've done a beautiful 5 bone prime rib on the roti and had most burners dialed back. I LOVE the way I've been able to sear decent-sized prime NY steaks (16-18 oz) on the sear station and set the steak over burners that are off to finish the steak to a perfect MR. When doing skinless/boneless chicken, I only open the burners up to half. Wifey loves grilled fish and the 470's burners dialed back let the fish bake as it crusts.
The beauty of the 470 is NOT the heat, it's the SS rod cooking grates, it's the even heat distribution, it's the rotisserie, it's the IR burner, it's the side burner, smoke box, sear station, fuel level indicator, slide out drip/drop pan for easy cleaning,,,,
I wish I had gotten the 670!
