Choosing a copier

I have been charged with choosing a copier for my department at work. I
am quite clueless about how to make a choice. We are just a team of 8
people requiring less than 10,000 copies a month, so a low-mid volume
b/w model will do (we have access to other machines for higher end
jobs).

We have shortlisted the Canon iR3300 and Xerox DC286 for starters.
Fax/Scan/Email
features would be nice, but are there disadvantages to having these
built in?

Any advice much appreciated.
