Canon Pixma Pro9000 ?

Hi, I'm really interested in getting the Canon Pixma Pro9000 and was curious
about the numbers of prints.

Would anybody who owns or works with one be willing to share this info?

I'm wondering how many 13 x 19 color (average quality setting) prints one
might expect from this printer?
Heck, I'll take any sort of info regarding any size paper for print output
that folks are willing to share.
Thanks in advance.
