I have an offer from Dish that I can upgrade from my current VIP 612 to a Hopper with Sling for no installation charge. Since both the Hopper with Sling and the Hopper 3 carry a fifteen dollars a month charge I wonder why I would want the Hopper with Sling over the Hopper 3 other than the free installation. Note that I have only one TV and I live in Florida. Am I correct that either one would require a dish upgrade to the hybrid dish, which should be better in the Florida thunderstorms we get almost every day in the summer?
