Multi-function Printer Recomendations?

worm eater asks: "My office is thinking about purchasing a multi-function printer/copier (MFP). We are currently looking at the Panasonic Workio 3510, but there is a surprising lack of reviews on the internet (there is one at ePinions). Has anyone had any experience with this model (which went on sale last month) or other similar machines? We are looking for a good B&W copier / laser printer capable of connecting to our LAN. The ability to interface with Exchange and send internet faxes would be nice, but not essential. As with pretty much any copier, we will need high quality support. Thanks in advance, Slashdot."
