I am an existing customer looking to upgrade to a Hopper (only)no joeys needed.Before I go online and speak to CSR,what is the going rate to upgrade(any specials).What do I ask for.My 722 is been acting up so its time to replace anyway..What kind of deals have customers been getting?Is the Hopper worth it??I dont mind renewing contract to get a Good deal.I plan on sticking with Dish..
