Hi
if it is 35mm
now then I suggest a 5000 or 4000 as they will cost you a
lot less. Up front. If you are going to dabble in MF then (especially for web sizes) you will also save money (even adding the cost of the two together) with the addition of a Epson 700 (or even a good used 4990).
Of course the 9000 is an excellent device.
The 5000 and the 4000 however have a nice tool to allow easy strip feeding that I do not think the 9000 has. This may assist in reducing time if you happen to be doing this for a business.
If you would like to see actual comparisons then have a look at my blog
here. Keep in mind that the sections represented are 4000dpi scans and with an inch and a half of width that is well over what you would scan for web delivery ... perhaps even what you would scan with 8x10 printing.
So for an overview of the image
I am examining this tiny portion (of the drum scan)
and the Nikon
The nikon 4000 actually does pretty well against such a benchmark, the Epson is not as sharp:
but when you resize them to be an appropriate section of a web sized scan that difference diminishes remarkably
