I'd also recommend getting a good monochrome laser printer. Samsung makes some really nice high quality models, and the toner costs aren't outrageous like HP's toner costs can be.
Brother would be my second choice (as miles said, the HL-series.) The only thing with these models is that once the drum runs out (usually 20,000 pages or so), get a new printer, because the drum will cost around the same amount as a new laser printer...
