The good thing about 6922's is that they have really long lives in the scheme of things. Usually 5000 to 10,000 hours. We all have our preferences but most prefer NOS. I agree with the comments about ebay.
Buying from here or audiogon is usually safe. Other good dealer such as upscale are tubesandmore.com and thetubestore.com. Sometimes echohifi has good buys. Some sites are fun to peruse but are way too pricey such as tubeworld.com.
