I actually purchased the Brother HL-5470DW for $193 no tax/shipping from BH photo video. The cost increase to me was worth automated duplexing/wireless and overall cheaper cost per page. Get the TN750 toner cartridge, and it estimates 8000 pages! Of course that is a high estimate, but lets say it is only 4000 pages.......that is only 2.25 cents a page! Half that if you get closer to 8000 per cartridge!
I actually did not want to fool with Printopia or anything of the like. Good reviews, but for simplicity's sake and not having to have a computer on all the time...I decided to go true AirPrint capable.
