What are the speakers you very rarely find in the Used market(Audiogon or Anywhere)?


I'm looking for Vandersteen Quatro CT, Wilson Sabrina or DeVore Fidelity Orangutan 0/93 or 0/96. I rarely find it or in some cases, before I make an offer, it is gone. What other speakers are a rare find?

@glennewdick - Can you please let me know the dealer name? I'm interested in getting any of the speakers I listed. I saw one Wilson Sabrina pair this morning but it is local pick up only. I'm speaking to him to see if he can ship if I arrange FedEx to pick it up from him but I would be happy to get the DeVore Speakers as well.
  I see O'93 pretty regular on Audiogon...Rarely O'96.  I happen to have O'96's still sitting in their crates in a custom color you've never seen...Guess I would describe them as a Honey/Butterscotch color with a Quartz/Burl finish. I also have Audio Note SPX Al Nico's which are so similar to the O'96's that I could part with the Devore's. If interested send me a PM and I can send photos. They certainly wont be cheap as the color was a 1500 upgrade.
Gershwins tend to be rare and ephemeral when they do appear. Same with Trenner and Friedl. Yes, there's a pair of the latter available on Agon now, but that seems to be an exception.
