There was a three part documentary (3 hours - yazza) on PBS a couple of days ago entitled "Black Coffee". While I only caught about an hour of the show, it was enough for me to order the DVD set and begin watching. I ordered the 3 DVD set (~$25) from these guys and it arrived in 4 days - excellent service.
