Printer-Copier Vendors – Who do you use?

We are currently evaluating new copier/printer device vendors for our companies use. Our curent use of printing and coying is on the high end, for example one of our black and white devices had over 900,000 pages printed. This new vendor would not only need to have good machines but also provide great service contracts, and some consulting on what machines best suit our needs would be nice. So what vendors are you currently using? Are you happy with them or would recommend them to others?

Thank you!
