It looks like some small mom-and-pop computer stores have been able to get small quantities, which sell out the same day they get them (which is why no one is listing any on their web sites).
So, basically you need to e-mail or call around a lot of small stores. Look for places that sell overclocking stuff, like Celerons pre-tested to OC, or Golden Orbs, etc.
I am doing so, and hope to get one soon. As stated above, the larger quantities should be starting next week.
