The second link that Chuck posted above is the page I ordered my last 2 from. They were out of stock as they are now, but I checked the "notify me when available" button and put in for 2 of them. It was only a week or sombeforenthey became available. At least that's how it worked for me about 6 weeks ago. They may not be stocking them at all and only order when they get a certain number of requests?
