I built one that's similar to this .
The grill is adjustable on the height above the charcoal. The 30" grill I've got will handle 12 good size rib eyes or 16 new york strips .

Charcoal is such a pain in the ass I never BBQ’ed after work.
Now with my propane grill and the knowledge of how to use it I cook every other night.
Grilling with propane is no different than charcoal; if you don’t know what you are doing the food is going to suck. If you do know what you are doing it is great.
