As we have discovered, imaging is a real can of worms with a number of
difficult tradeoffs/decisions to be made regarding resolution, processing
speed, storage, retrieval etc.
While I have no specific comments on the brands of equipment you are
looking at, I strongly advise checking the processing times on any
scanner you propose using as there are very significant differences which
can make huge differences to productivity over a period (I assume you
have already made your decisions on resolution capture quality).

Re CD-ROM machines- again the write speed for a CD-ROM varies enormously
from a couple of hours down to 10 minutes or so and there are various
other considerations like the need for a dedicated pc with  a large hard
disk and lots of memory etc.

In view of the cost of consumables and capacity of the media, we are not
currently using CD-ROM but have decided to use DAT drives instead.
The drives are much cheaper (as are the tapes) and the capacity is triple
that of a CD-ROM.
There's no easy answer though depending on retrieval and archival life of
media etc, etc, etc........!

Good luck!
