I don't know why everyone has problems with their priting costs.
Got a Brother HL 2030 since 2006. Payed about 150€ back then. Printed everything with it, including all stuff I needed to get my degree (projects, script, thesis, etc) and all the private stuff I did. Only this year I replaced the cartridge and drum for about 30€. Now it prints like on the first day.
I have a HL-2170W and miss the duplex the 3 times a year I use it. I was mostly letting people know that they more or less still make the same printer (at least, as far as I know the new ones have not become crap).
The HL-L2340DW comes with a starter toner cartridge that is good for 700 pages, so it is not a terrible way to have convenient printing for a decade.

Best purchase ever.
