Either way you go it will be cheaper than cable and the picture is a lot sharper too.

I got the Dish Network dish (4722) I was wanting AC-3 (a.k.a. digital dolby) sound and didn't want to pay a lot for the dish (Total Cost $54 - 4722 / Dish / all the Cables / and Shipping!!)

Setup the dish myself, not that hard. Bottom line I'm sure you will be happly with either.
