We have a Brother HL 1850 that has been nothing but trouble -- we have had it for 10 months and has been replaced once and in for major service another time. Now over the weekend a small piece of glass -- about 8 inches by a half inch -- broke off inside. What IS this, anyway? It is under warranty, so we will send it off again for repair, but this is too strange. Anyone have recommendations for another printer in the same price range that will be more reliable?
