The retail model for the SB6141 is:(Available from Amazon directly)
SB6141 from Best Buy for same price:(If you don't want to deal with shipping)
Kind of expensive though.
Modem that is often recommended by people on this forum:(Only available from non Amazon sellers)
Too bad the DPC3008 isn't $69.99 on Amazon anymore. I got it during that time and it's been great so far. Hasn't dropped out yet and runs pretty cool(I stand it up on the side and usually only the top is warm, the sides are slightly cool)but, I really hate how the information page doesn't give you that much information about your channels.
DPC3008:(Available from Amazon if you click on them)
Most people suggest that you make sure you buy directly from Amazon when using Amazon though when buying modems.
