I asked for a reason. When I bought my largest gas grill it had four regular burners, a ceramic infrared searing burner, and an infrared rotisserie burner as well as a side burner for pots and pans and also a gas oven. After a couple of uses of the ceramic searing burner (which I love) I decided to check out what the replacement cost would be for those. At that time they were only about 45 USD each. Now they are hard to find and over 200 use each. Over time, especially if you are a spice junkie, you will get drips and things that will drop onto the burners and potentially clog some of the tiny holes. Even the wire guards on top will potentially suffer. Eventually the ceramic will start to break down. By that point in time the parts might be hard to find, as in my case.
So, some unsolicited advice: Check into what replacement burners cost now, and if you find them reasonable, buy a set especially if you grill a lot. Never get a pressure washer near them, and let your burners run longer than when you are just done cooking food.
Enjoy your new grill Kev!
