Our Son of Hibachi has been around since my college days (early 70's) and is still our 'go to' charcoal grill when camping. Its compact (17x10x5 closed), indestructible (mostly cast iron), performs in windy conditions (fold one side partially over), lights quickly (grill acts a a chimney starter), has multiple height adjustments, cleans up easily and has enough grill surface (170 sq in) for two. Supposedly, you can close it after use and save the charcoal but I've never had much luck with that - maybe the 'snuff bag 'which I don't have helps with this. It is fairly heavy at around 15 lbs. I started using coconut shell charcoal last summer and really liked it but its no longer available at our local Lowes store.
I also have a complete Cobb set up that does a great job for roasts, beer can chicken, stir fry, steamed veggies etc but not so much for steaks, burgers, chops or dogs.
