I use Ozark Oak at $4 for a 10lb bag, or 40 cents a pound. Even though I've only tried a few other brands, I like it real well. It burns even and burns hot, and doesn't fill my firebox with ashes in 2 hours. Made in Arkansas I believe and I plan to keep using it.
Here is a site that rates lump charcoal. Ozark Oak is ranked #1 (another reason I tried it), but there are several good brands, and these guys provide some thorough commentary and pics.
i think i have an update on that original charcoal. tried emailing them...no response tried calling the phone #s on their site ...no longer in service.. i would take that to mean they are maybe out of business?
