The biggest criticism with using charcoal to grill is waiting for the coals to heat up. The Bison Airlighter speeds this process up mightily.
The Airlighter has a butane torch that blasts the coals and lights them in under ten seconds. THEN the air lighter's fan turns on, spreading the fire out to the rest of the coals as they heat up in a minute or less.
On top of that, you can utilize ThinkGeek's 20% off 4th of July Coupon to drop the price even lower.
