What used speakers raraely come up for sale

Lets keep it under $7,000 used, but interested to hear what used speakers rarely get listed for sale because they are so sought after and if they do appear they get snapped up very quickly?  Cheers
There was a gorgeous pair of Hawks that were listed and re-listed here for months. Perfect condition and the price was right too.
There's Obelisks on ebay now.

Lirpa Labs is a fictitious company used as a joke since the old Audio magazine's October issues which listed almost every audio product made at the time. Maybe even before that, but I don't know.
Spell Lirpa backwards and you'll understand the foolish joke...
Yea gentleman,  I fell for that one a minute, until I rationalized  the specs as being preposterous. LoL!
