When this thread started, I posted about our Pyromid grill, then out of production.
I just discovered that the grill is being manufactured again, and the 12" and 15" sizes, under the Ecoque name. The Website is

The big benefit of this grill is that fact that it folds flat to less than 1" thick and is easy to store. You can see how we do it (it's in the green bag) in the piucture from my gallery:
Ours has lasted about 25 years so far, and will no doubt outlive us. Cooks good, too.
FYI.
