well the people you see trying to unload them think they have something so special that they try to command ridiculous prices for them, but you gotta wonder or ask them...................If it's so wonderful why you tryin to unload it? But they really were just terrible. They had one huge round burner like a turkey fryer burner, Above it there was an inverted "cone" shaped piece of steel. If you dropped the lever down it dropped that cone down into the burner to deflect the huge jet of flame to the outer part of the grill (indirect heat). If you brought the lever up the flames shot out in a giant jet directly under the center. (direct heat). It used lava rocks as well. They either did not cook or incinerated everything you put on them. No joke. It was about the singular most awful piece of gear ever madeInteresting stuff.
Sounds a bit like the Star Wars Holiday Special -- best to forget it exists, but still kiiiinda want to have one.
