Another Brother laser vote. Estimate that I've bought about 15 of them in the last five years, for small offices in my company.

I've avoided the least expensive lines, which used to be machines in the 7xxx series. The paper feeders tend to be flakey. However we've had good luck with those in the 8xxx and 9xxx series. Decent quality non-OEM toner is available on Amazon, and its cheap.

Only thing about Brothers that bother me is that the "Replace Toner" messages come on too soon. Googling the issue reveals hacks which trick the cartridges. On some models all it takes is a half inch piece of black electrical tape, and you can get another 500-700 copies from a cartridge after it goes into "Replace Toner" mode.
