Has anyone got experience/recommendations for the current crop of home/small office all-in-one laser printers? Looking for a mono laser printer/copier/fax with duplex and ethernet. Something like a Canon i-SENSYS MF4570dn, or its nearest HP equivalent. Not many of these devices available as refurbs, so looks like I might have to buy a new one. I normally look at the PC magazines "best buy" reviews for kit, but unfortunately they are usually rubbish at testing the running costs of printers - i.e. often users comment that a certain "recommended" printer actually cost a fortune in toner because of its warm-up routine or similar. Hence it would be useful to hear about anyone's experience with a particular model. Thanks all..
