I BBQ some hamburger the first time to  break in the new porcelain grill and they turned out perfect; (purchased for our new RV)  -   the next night  BBQ a pork tenderloin with plum sauce and it turned out with just a little "pink" in the center - "perfect"!  On my other Weber's I use use to the cast iron grill and always liked it  -  but I like the new porcelain grill better  -  easier to clean and still leaves the "grill marks".  I am very happy and also just ordered another porcelain grill for my older 2000 model that still is cooking and enjoyed a perfecy salmon!!!!!
