Just curious...I noticed that I could buy a Dish Networ ViP 211 receiver from Amazon for $150...is there any reason to do that at all? The way I understand Dish's website, it looks like I will pay $7 (I already have Dish service) no matter if I own my receiver or if I "lease" one from them. I didn't see any additional lease fees, so why would anyone spend the extra money to buy one? Am I missing something?
