I've had good luck with Oki C6xx and C7xx color lasers, purchased off-lease. Large, heavy, and the office lights briefly dim when the motors start to churn, but none of this phoning home nonsense. Most toner works without complaint, though my source freely replaces the odd cart that doesn't. Not sure of newer models.
By comparison, SWMBO's HP multifunction inkjet is an unmitigated PoS. Won't do third-party toner, needs a new driver installation every couple of weeks, and phones home sporadically. Probably a good thing that the axe is inconveniently off in the garage when this happens.
