The manufacturer has been saying that the gen 3's would be out of stock until 2015 since at least October.
They do exist, but are extremely hard to find. I wanted one really badly back in November and had been looking all over for weeks. There were a few crazy expensive ones on eBay, and then suddenly a seller popped up with 10 new ones. They were high, but less ridiculous than the others listed, so I jumped on one, as did a half dozen other people in the next 24 hours. After that run he raised the price $50 on the last few.
A few weeks later one of the retailers that I'd set a stock notification alert on suddenly got some more in, at standard retail pricing even! So I boight another one!
The moral is not to give up. Maybe this is the De Beers strategy; create an artificial shortage to keep prices high and make a ridiculous profit!
