Any porcelain-coated anything will not last very long. I learned that on my first couple of grills. A few cycles of use, and the ceramic coating develops micro cracks, and pretty soon the interior non-stainless steel rusts out and it all falls apart fairly quickly. Solid stainless (good quality stainless) is the only way to go, especially for the grates. They'll last for years, and be cheaper in the long run.Genesis E330. It's just the porcelain-coated steel drip bars. Everything else is fine.
