I just ordered a set from B&H Camera Store in NYC. These are the Lunt glasses that are mentioned in the article, but are also identified by NASA as "safe" [1]. I'm hoping that B&H does not suffer the same counterfeit problems as Amazon. Shipping from NYC to the Bay Area is still a concern though (I'm a lot closer to NYC and just got the e-mail that they shipped on yesterday's order).
