I was not quite sure of you were referring to home or commercial at first, then someone mentioned the BGE (Big Green Egg) and I realized this is for home use.
A agree, the BGE is a great unit, you can grill at super high temps, BBQ Low&slow, or do just about anything on those BGE's. They are not cheap by any means, but well worth the investment. I do not own one, but I have used them at other peoples homes and they are impressive
Check out this site>>> NakedWhiz dot com (this forum will not allow me to post hyperlinks yet, but you get the idea) the guys that run that site are BGE maniacs!! and they also have an entire website devoted to BGE cookery and information and rating on lump-style charcoal. You can even learn about electronic controllers to maintain temperatures in charcoal-fueled equipment. I use a "Stoker" controller on one of my Commercial mobile BBQ Pits, check the controllers out too. Imagine doing an overnight cook for pulled pork, and not needing to check on it, the controller does it for you, and it can alert you of temp problems via the web, or cellphone messaging. You can even change temps on it using a web-phone or laptop from anywhere in the world that you have web access.
IMO, do not screw around with briquettes when cooking with charcoal, once you learn what the stuff is made of you'll understand why it produces so much ash and it's heat potential is so limited. Use lump, be happy!
