I was at Sam's today and saw a kamodo-style cooker named a "silver keg" (I think). Anyone seen one of these? I can't find any additional info online. Not sure what it was made of, the kids were pulling me, but it had an interesting gasket. The gasket was made of silver material and compressed when the dome was shut making an excellent seal, I have no idea how it would hold up to high temps, but the thermometer went to 800.
