We currently have a KM LD6500. We are in our 3rd year with it and will be replacing it next February. Now is the time to gather information. I am looking at upgrading to a larger machine, KM 7000/8000, Canon 7010, Xerox 7000/8000 or 800. I want user experience. How reliable are the machines, Is the tech close, is service prompt. Color consistency (ours needs reset after any internal maintenance and month to month is all over), Color text registration, heavy stock usage. any input from real users is greatly appreciated.
