Wow, thanks for the prompt reply.
So as far as I can tell (Christmas spirits over here so lunches are mainly liquid) it has four levels and in the supreme you get grills for main and middle level. You can then buy the additional grill which allows cooking at main + 1 and at the lowest level (searing only).
Do you know what the temp differences are between the main, main+1 and middle level (using the heat deflector?). I understand that the searing grill is superhot...
It looks like a GREAT BBQ...
