I'm about to purchase a scanner, and have narrowed down (i think

my choice to the canon D660U.
i'd be interested to hear from anyone who has used one.
whats the scanning software like to use?
any probs with mac os 9.0.4?
is it easy to set up custom scanning settings?
I'll be scanning prints for web work, and the odd print job (I'm assuming scanning a 35mm neg/slide on it will only produce something good enough for the web.... tell me if i'm wrong.)
