If you can live with your locals being in SD and you truly do not have line of sight to the Eastern Arc, you could stay on Western Arc.
I just called them, I still have 5 months left on not getting receiver fees and they are not switching me to eastern arc so it is a plug in. I don't have locals. They are sending me a 512 and I'll think on switching to the phone company for another few months.
I got nothing against dish, I have a feeling that I'll be going over to the phone company eventually based on pricing.
