I have a small, portable infrared propane grill I bought to use on my sportfishing boat.
I bought it because the infrared feature vaporizes most of the fat and grease, which are problems on a boat. It works very well, but you cannot get a true black and blue steak (aka: Pittsburg - burnt outside, still rare or even cool in the center) like I can get on my Weber Summit with sear burner (or better, if I'm not feeling lazy, a Weber kettle.) The winning feature of the infrared is reduced, almost nonexistent flare ups, but to get a black and blue steak you need the flare up!

Also, FWIW, my Weber grill was starting to go a couple of years ago, the burners, flavor bars, grates and even the box. I called Weber, gave them the serial # and they sent replacements free of charge. The burners, flavor bars and grates were easy and got changed. The box was going to be a pita, and I tossed it. My original firebox still has several years left, though it has one hole in it. So maybe Weber will provide free parts?
