[3dem] Zeiss SCAI/ ZI Photoscan discontinued

[Steve Ludtke]

Hmm, I think I might have been called on this before... I think I may be
remembering what we paid for the 8000s just before the 9000s came out. Indeed,
the current price is closer to $2k. Nonetheless it is considerably less than
$130k...  Sorry for the confusion.
