I'm not sure of the protocol for self-promotion, but in my Oscans business in Australia we are still using big old Kodak HR500 Plus scanners that have digital ICE cleaning for Kodachrome.
We were in the process of considering a Flextight, I wish I had jumped sooner. It is a better scanner in terms of technical quality, though much slower and without a cleaning process.
As others are saying, we will keep scanning until we no longer have functional equipment.
Sadly, that day will certainly arrive before everything is scanned.
