The APO-Lanthar Bessa II is pretty darn rare. Only 34,500 Bessa II's were made, and the APO-Lanthar was the rarest by far of the three lens options (Color Skopar, Heliar, and Lanthar). I've never seen one. I can't imagine actually paying the asking price for one of these, but I suppose someone may at some point.
I have a Bessa II with the lowly Color Skopar, and it's plenty capable for my needs. Not as sturdy as my Super Ikonta, though, which is 20 years older.
