6 months ago i set up a small workgroup and got a Lexmark Optra T520 network printer for it ( at pricewatch you can get it at around 570 US incl. shipping). Since i set it up there, there has not been one single problem, + they have heavy printing needs because it is a refugee asylum office. They just needed something that works, with no fuzz or anyone in the area with any computerskills if there would be any problem. So far it has done the job perfectly, with no hickups at all.
Just my 2 cents if it would be an option. From my experience i fully recommend it.
