I have a slightly different model with duplex and I want to chime in that Brother makes excellent laser printers - at least from my experience. I had this baby for 3 years now, and I am STILL running on my first toner cartridge that came with the printer.
Mind you, I print casually, like when I have to print out an odd page from the internet, or when I print my college homework or scanned documents for mom and dad, but still I am sure it accumulated into quite a volume over 3 years. I heard these cartridges are designed to hold less toner than those you buy as a replacement after your 1st one ends. I just dont feel it! I bought my Brother for $120.. or was it $160? And it more than paid for itself compared to my inkjet canon which I used to spend around $60 for every 2-3 months. So I dont have color prints.. Who cares? I rather order color prints from an online service once in a great while than to waste money for ink. Also ink cartridges would dry out on me if I didn't use em. Toner doesn't dry out, and doesn't spoil!
Oh and did I mention my Brother never jammed, even a single time? And I even abused it a little, putting in slightly bent/creased pages that already had text on the other side...
I probably sound like a Brother spokesperson by now, but believe me, I am NOT, I am just so happy with my purchase, and I highly, highly recommend it.
