Huh? That's ridiculous... I grill several times a week, I don't have time to mess with charcoal. I turn 4 knobs, hit a button and go back inside to finish prep-work. You don't have to have charcoal or spend inordinate amounts of time to make a good grilled meal for your family, even if time is tight.
As a matter of fact, tonight I'll get home from work, and with 2 young kids running about under my supervision, I'll hop out on the patio, light the grill in 10 seconds and be back inside to get dinner ready for when momma gets home from work. 2 minutes later I'll go back out to the patio with my fully pre-heated grill and a plate full of burgers to throw on. And when they come off the grill they will be ALMOST as good as any burger cooked charcoal. Life doesn't have to be complicated, some people just choose to make it that way.
IMHO, my ideal grill setup would be a hybrid grill; one that has a LP burner for fast, convenient heat, but has the ability to use charcoal exclusively, or a mix of both LP (main heat source) and charcoal/wood for the smoke flavor. The problem is that my ideal grill isn't the ideal grill for the masses so target market would be people looking for the convenience of LP with a little of that wood-smoke flavor of a charcoal grill or smoker.
FIFY. Charcoal does taste a bit better. But sometimes its not worth the extra hassle to get that extra flavor. Its like the difference between a ground beef and a ground round burger. The latter is better but the former can be acceptable too.
Check out my second link in my post above. Its a hybrid, with a crank adjustable charcoal platform. I almost went with that one but with other things on my plate, I didnt want the added expense for no more than I would use it. I too dont have much time and the ability to turn a knob and go appeals to my lifestyle.
There is also one at lowes which is marketed for both. it has a tray that drops in on top the burners. Drop in the tray, add charcoal, then use the burners to start the coals. But to me that seemed like it would be asking for trouble with the burners given the corrosive nature of charcoal ash.
Sometimes to get what you want done right, requires more than one purchase. Good luck.
