We have the e125 which is the newer model of the 9110 and I have been throughoutly impressed with it.
Able to do overprint offset work and glossy substrates are a big plus compared to the rest.
Rip speed is great, functionality is good, interface is a bit to get used to but fully functional.
It is a workhorse, it just runs and runs. Little or no maintence over long runs, service is really knowledgable on it.
It supports all of the XRX (docutech) commandset of postscript commands plus Kodak's equivalent KDK commands to control output so you can move hand written postscript over with ease. Handled a 4 stock multiple tray pull job for us flawlessly.
Can print on tabs including mylar tabs which is huge, and they actually fuse on the mylar, go figure.
Best of all, you aren't limited to Kodak paper, oh wait they don't sell paper

It will run almost anything, we run a lot of junk copy paper through it and it performs like a champ. Can easily switch to 80lb cover and run that too.
