I use this pan that I got at Wal-Mart for $5 and the C-bolts at Home Depot for $1!
I wanted it not so much because of the fat dripping on the coals but I wanted to save the drippings to make a gravy.
I also fill it with apple juice when a do BBR or fill it with the brine when I do Turkeys or Chickens.
I've been very happy with it and noticed no loss of fuel efficiency!
Give it a shot, the only part that sucks is cleaning the pan when I forget to EVOO it!
