Proth5's new oven perhaps?

What do you think of this?  Can you find something similar in Okinawa?  It is designed to fit over a burner and heat comes up through the selected pieces and reflected down in the middle.  I think 6 pieces including a support ring and grill tray, baking tray and two piece funnel device plus a lid.   I saw 3 different sets here in S Korea but this one looked like one could bake rolls and horseshoe baguettes in it.  You could bake more than bread in it too!  You can do a chicken or shrimp and grill some vegies and heck, have a grand 'ol picnic with this little gem!
