There are newer boxes available, but the Cisco is the fastest or at least my 8642HDC is. Samsungs also suffer from memory leaks. My Samsung 3272 can get real slow at times. My Cisco 8642HDC and Samsung 3272 have a 500 GB HDD, and there are Motorola DCX-M boxes with a 500 GB HDD as well. If you have a eSATA drive on your 8300HD, then keep it, but TWC San Diego is slowly starting to phase out the 8300HD, but there are 8300HD's out there, if you desire eSATA.
