The SB5100 has served me well for three years. But Comcast has talked me into its Digital Phone box, which is also a cable modem. So now you get to buy the ubiquitous Motorola Surfboard at rock bottom prices. This cable modem has been the basis of a home network that served three laptops, two PDAs (Pocket PC & iPhone), three gaming consoles (Xbox 360, PS3 & Wii), and two portable gaming devices (DS & PSP). It is a workhorse and can handle anything you throw at it.
