Slightly off topic but I'm just going to throw it out there. If you are cooking with charcoal I highly recommend a Kamado style grill aka big green egg (BGE). Once you get one of those you will never go back. It is extremely efficient with charcoal.

There is one made by Char-Griller that is dirt cheap and light that I use year round (another advantage of the kamado is it can be freezing out and you can still grill fine).
