IF your using a 5 LNB set up and are comfortable setting it up and have room to store it ... thats the one I would go with, you'll get everything you currently do.
Otherwise go back to a slightly smaller 3 LNB set up, old style, or you can venture up to a NEW version 3 lnb set up.
All depends on what you can set up easily enough.
You will get your locals till you go outside of the spotbeam for your area.
There are two key things we need to know before answering accurately. What's your zip code, and are you looking to receive just SD signals or HD signals also?
