Hi Guys, Need your help. Does anyone know about these grills? I know they get hot and a lot of restuarants use them to grill there meat. Are they worth the expense , $1600, and are they worth it? Do they seal in the juices THAST much better , or can I get the same effect using lump charcoal with a cast iron on my Weber Performer Kettle.I probablt think IF they were worth it, everery afficiano would have one. All help is apprecited!
