I bought this Brother HL-2270DW a while back, also around $80 at the time of purchase, and it's been serving me well. I figure if I ever want color prints, I'll get them done somewhere. The need hasn't arisen yet.

I keep a spare high-yield cartridge, and after needing to swap one out, I just wait until the price drops to below $40 and snag one. Not saving a ton, since it usually overs around $45, like right now, but hey, $5 is $5.
