Where to get Svetlana 300b's

I just had a listening session with Western Electric 300b's and they were absolutely fabulous. A little "lightweight" (compared to my TJ Golden's), but OH the delicacy, inner detail, ease of presentation, and staging. That on Marco's quicksilver amps and a pair of Klipsh LaScalas.

Anyhow, unfortunately I don't have the $$ to buy a pair of WE, though I hear the Svet's are very good too. Problem is, I can't seem to find them online. Anyone know of a good source?

Thanks, Peter
