Whoops, posted too soon. What I was going to add was that the choice of wireless routers is greater than pure wired ones, and the prices are similar. I would therefore suggest that you don't rule out a wireless version.
No advantage in a purely wired modem/router. They are no cheaper, if you can find one, and you can just switch the wireless off if you don't need it. If you get a smartphone or a Kindle etc then you must use wireless so best to have it available in case of future need.
