I currently have an HP Photosmart C3180. As I student I am doing lots of text printing and the C3180 uses its black cartridge very fast and at $13 a pop it's getting old replacing it so often. So I am looking for a cheap B&W laser printer at or around the $100 mark. Speed isn't an issue, just want something cheap, reliable and good on ink. I have been looking at the Brother 2140-it's on sale at Staples.com for $80. Any recommendations?
