I saw this earlier this evening. I'm not really in the market for anitum, and that's way more money than I'm willing to sink into a plant. But it did catch my eye, even before I noticed the price.
I didn't realize there were legal/legit sources for anitum in the U.S. Last I read (probably on here) is that it was easy to skirt the restrictions by labeling plants as adductum v. anitum.
I've only purchased a parvi from that Ebay seller, but I did end up with a nice plant for a decent price. And his multifloral paph listings have been plentiful, and generally well received in terms of # of bids, so if I were looking for anitum, I wouldn't hesitate to purchase one from him.
