Looks like you can now buy Clay King from Bonsaitonight.com. I've been very happy with this brand and think it's one of the best available, very good quality akadama. You can mix it with pumice/lava to get a drier mix and make it last longer if you would like. I think it's somewhere around 60-70% akadama, the rest is pumice/scoria. Cheaper at the nursery in Nor Cal.
