Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem for $64.99 shipped.  Here is a screenshot for your reference.  This is a newer and speedier model cable modem than most, with support for IPv4 and IPv6, and speed over 100Mbps in each direction.  Having your own cable modem often means you will not have to rent one from your ISP with a monthly rental fee, but it is important to check with your ISP to ensure compatibility.  At the time of this post, 118 out of 124 user reviews have given it 4/5 and 5/5 ratings.  Most places have cable modem for about $93 or more.

This deal has expired as the price has been raised.  Congratulations to those who were able to get in on it.
