Hah! A smaller version of this is the most common oven street vendors use in my area. You can buy these small round ovens / grills everywhere for about a dollar. We used it for some very basic bbqs and they get their job done.
Only cooking tip I have is to wait long enough that it gets heated up properly. It is fantastic for smaller bbqs and does keep the heat for a good amount of time. It gets so hot that wooden skewers are a big no no of course.
