Got a Lexmark e250dn printer. Fab does duplex and is on my network as well so when sat on any PC at home I can print out without having to start up and carry a printer around the house (I've got 3 PCs and 3 laptops!). Cost me £85 on special offer a couple of years ago, very cheap to run, looking to buy the e352dn when I need to. Wife loves printing things out double sided as it uses half the paper. Only trouble is the network settings got corrupted and I can't reset them so it is off the network at the moment but when the toner finally runs out I will replace with the e352dn.
