I scheduled an upgrade to a Hopper w. Joey in a week or so. I just received an email telling me that I'll be getting a receiver that the Hopper I am getting is a Hopper w. Sling. Looking on the Dish upgrade receiver page it looks like there is no cost difference to getting the one w. Sling. So, since there doesn't seem to be any cost difference I am wondering if there is any harm in getting this receiver w. Sling. Or should I call and tell them I want the regular Hopper?
