The value of the Carryout is that you can use it with different satellite services. Nice if you aren't committed to one. The downside is unlike the Tailgater, it requires a separate power feed so you will have two cables to run.
If HD and Direct are important to you, be sure that the Carryout will support HD when subscribing to Direct. I know there is a Tailgater type unit made for Direct but it will not support HD due to Direct using a different frequency on their HD satellite.
