I like to use a steel chimney with wax starters or crumpled paper.
If I cram too many pieces of charcoal in the chimney, not much air circulates and it takes a long time to get going.
Solution: place a used toilet paper cardboard roll in the middle and pile the charcoal around it. Even after the roll burns up, the charcoal seems to stay in place with plenty of air circulating for a quick start.
