holland has a cast iron burner and I believe a lifetime warranty on it. A bigdog stainless holland is $950 or so. I picked one up for a friend's husband's bday a few weeks ago. Many local ACE hardware stores carry them.
Just checked, yup lifetime warranty on burner.
from their site:
People often ask, 'what makes the Holland Grill different?' The difference is inside. Holland's unique, indirect cooking system gives you moist, juicy food--all without the hassle of flare-ups!
1. Holland's signature smoke stacks help pull air into the grill where it is heated and circulated much like a convection oven. They also allow enough heat to escape to maintain a constant temperature in Holland's hassle-free one-temperature setting.
2. The stainless steel cooking grid will last a lifetime, is easy to clean and its diamond-shaped pattern prevents small food items from falling through.
3. The rust-free aluminum drip pan catches the juices from the food where they sizzle and smoke back up on the food, giving it that distinctive Holland-Grill flavor. There's no charcoal, lava rock, ceramic tiles, etc. to clean. The drip pan slopes slightly to channel all the excess grease down a 3/4" drain pipe and away from the flame.
4. A stainless steel deflector plate spreads the flame out so that you have a relatively even heating pattern.
5. The heart of it all--Holland's cast-iron burner is guaranteed for the life of the grill. No more replacing rusted out burners every year! Now that's hassle-free.
