I owned a Canon ipf8000 for almost four years and it performed flawlessly. I recently replaced it with a new ipf8300 and it is also performing flawlessly. I never had so much as a single head clog in all the time I owned the 8000. It had a few design quirks that were corrected in the 8300.
When you look at size and construction, it seems quite apparent the Canon is a far more ruggedly constructed machine and probably overkill for many users who won't be using the machine in a commercial environment but I certainly have never had any regrets.
If you research the comparisons and comments on Luminous Landscape and other printer forums you'll find that most people now consider Canon to have matched or surpassed Epson in image quality and longevity. One drawback of the Canon IPF series is the lack of a straight paper feed path, so some thick papers may not work well nor can you make metal prints. Those issues are not a consideration for me as I print from roll media almost exclusively.
