I've had a Samsung ml-2525 for probably ten years, it works great. Sadly Samsung sold their printer division to HP. HP even removed features from the driver, they took out the ability to do manual duplex printing.
HP doesn't sell toner for my model anymore but I was able to find it from cdw. I figure the printer will outlast my ability to find toner for it.
This just confirms my already existing stance to never buy anything from HP.
