Given a choice, I'll pay a bit extra (but not too much extra) for instant-light charcoal then add a little lighting fluid as well. Don't waste your money on gel. You'll do just as well with crumbled up fire lighters, although you shouldn't need either with instant-light.
I use a chimney starter with wood shaving for the starter no need for any chemicals at all...

Another advantage of lump wood over briquetes is that you can then use the ash in the garden, where as with briquetes you never can be too sure whats in them.
