Thats the one I got worked good for me the last year. Think it was 55 bucks at canada computers. I like the idea of a 2nd line you can do with it.
op if you already got a router and just want it for the home phone you don't need one with a router built in. One the one or two ports thing will with 2 ports you can have two phone number. Exp you can have your home phone on one port and a business phone on the other port.
