If you don't need color printing, I suppose Laser Printer?
I have been using Samsung 4500, roughly around $199 shipped. (600 dpi/8ppm/35Mhz/2mb)
Or you can get Samsung 4600, for extra $30. (1200 dpi/8ppm/66Mhz/4MB) <-seem like a better choice.
Both using 2-in-1 Drum and toner design for 3500 pages.
