I bought a new pair of LCD-2's for $800 from http://www.razordogaudio.com/ and I am completely blown away by them. I have never heard anything like these and my favorite headphone before now has been the already amazing HD 650's.
The serial number of mine is 5423381 and it was made in made in December 2013 according to the warranty documentation. Do I have the latest version?
Mine is 5422xxx and it's the fazored one, so yours should be fazored too.
