Top Ten Reprographics Companies in the U.S. ???

Someone e-mailed me the other day and asked me this question:

In terms of annual sales revenues, which reprographics companies in the U.S. are in the "top ten"?

I'm pretty sure (well, let's say, almost certain) that these companies are in the top ten:

American Reprographics Co (ARC)

Thomas Reprographics (TR)

ABC Imaging (ABC)

National Reprographics (NRI)

Service Point USA (SP)

Anybody out there willing to venture a guess as to the others that would fall into the top ten?
