Query: Check price of toner and drum before purchase

As with all printers, it would be a good idea to check the price of consumables before purchasing this printer. This printer (actually this print engine, as it is used in several other Brother models) has a lower cost than some other Brother units, but you will make it up over the life of the printer as you buy higher-priced toner and drum units. The toner and drum units for this printer cost more than those for other Brother models, and don't last as long. Consider your printing needs and spend more upfront if you will be printing a lot.As long as you expect this going into the purchase of this printer, it is a great unit. It works as advertised, and Brother has very good drivers under Mac OS X. For the money upfront, you can't beat it. For the future cost of consumables, you may be able to find a better model for your needs.
