HP usually has a cheap laser for under/around $100, check their online store. They also have refurbished printers cheap too. I got my 1020 for $120, free shipping right to my door. Toner cartridge is around $70, but lasts a long time. Have looked at refilling or alternate brands.
I use the Pulsar paper, which I'll cut each sheet into quarters, since I do mostly small boards, and the printer doesn't do paper widths under 3.5 inches (or around there). Thin traces come out solid and even, really thick traces or large areas are a little speckled, but still work. There is some TFT films and foils you can put on the toner that pretty much fixes this, but I usually skip that step. And lastly, if you figure on doing lots of boards (usually do 2-3 a month), suggest a heat laminator over the clothes iron. I got my little 4" model surplus under $25, and worth ever penny. Only failures were do to fingerprints on the copper (rounded areas on the edges), but it's been a while.
