Toner refills may seem expensive at first, but in the long run they save money compared to inkjet refills. And I think OEM brands are worth their money. In the days of inkjet printers, I learned not to save money by buying run-of-the-mill refills that would subsequently clog the printer nozzles with inferior items. I'm not sure if the same applies to toners, but I feel more secure using OEM replacement cartridges and they haven't let me down yet.
