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?

Any Magico model! Especially considering how many are sold in the USA, it is very rare to find them used.
Here's a beaute...I have NEVER seen a single used pair of T+A's amazing electrostatic hybrids, The Solitaires, for sale!
Fat Julian in Atlanta told me about the Fuselier speaker...never heard them.
i miss his record shop.
Original Gallo Reference II's 
Or what some audiophiles consider an even better sounding speaker:  Nestorovic 5AS Mk IV
