Wow, given the date of your post I'm sure this reply isn't relevent to your question. But I'd love to know what you ended up purchasing and what your experience was.
FWIW, I used to market and support CPS printers for Oce'. Net net, they're fine for general office use but not appropriate for graphic arts enviros. Yes the color can be great and the calibration thing is true. It'll also print onto a variety of textured stocks but the one thing it cannot do consistantly well is glossy. The streaks are terrible and as of a year ago at least they hadn't licked that problem. They also couldn't handle greater than 10 pt. stock. Not sure what your $150K price quote represented (a 2-fer?) but the lowest price I could quote was $80-100K, including Fiery. So between that and .04 per click, for 31ppm that's pretty expensive. Many of the commercial printers I spoke with just couldn't see themselves making any money with them. They also commented on the fact that the colors weren't particularly saturated; no pop. The output was more complimentary to offset color then xerographic color due to the Copy Press process being more like the offset process.
