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?

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
Vandersteen Quatro CT Available Used $12,500.00 Customer upgrading.
Vandersteen pricing is going up. Quatro will be like $18K. You snooze, you loose....
I have a Pair of T+A Solitaires for sale 1000SE In Carbon fiber. $32000.00Dealer Demos.
Vandersteen Audio gives very little mark up as they are priced very conservatively in the market. Richard is the Costco of Audio. Other manufacturers would have priced the Quatro for over $25K. Buying them retail is a bargain.
