Second-hand Fujifilm shortage on ebay & prices going up?

I suspect some commenters are using "collect" different ways.  While F digital may not be "collectible" in the Antiques Road Show or Sothebys auction sense, some devotees do collect---be it to use or not--cherished past models.  And the X100 series is probably the leader in that regard.

And yes, I suspect an increased percent of these used sales are purchases for use.

First reason--inconceivable as it may be to many on this forum, there are serious enthusiasts who do not need or want the ever-increasing tech super-powers in the newest models, and for whom 16mp is ample. Not to mention, dismay with the smartphone-centric haptic\UI changes in some latest models.  I personally will never purchase a latest issue stripped of a 4-way directional.  For models where this and other disagreeable amputations and alterations are occurring, I will purchase only prior generations.   And I am not alone.

Couple that with second reason, hefty price increases on new issues, and shift to high-end market focus by not only Fuji, at a time when inflation is out the window and serious recession\economic crash is a very real possibility for many shoppers.   Recession and inflation, like supply a chain shortages, operate to raise used-good prices, not lower them.    But even with the used increases, a pristine X100T or X100S is a bargain compared to some of the new stuff on the horizon.
