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?

XStatic full range electrostatics as there were less than 100 pairs made (awesome sound BTW).   Triangle Stratos Volante 260 is another great speaker as was Gale.   I also don't see a lot of Ohm's higher-end speakers for sale.   All of which I still own or owned.
Snellc5 bought them in 1997 still listen to them ever day. Just purchaset a McIntoch MC452 can’t wait to get it hook up to old Snells
