I'm a long-time continuous Dish customer, starting in 1998. I pay by credit card Autopay. I'm wanting to upgrade from Hopper 2 to the newest model of Hopper 3. If I phone Dish and tell them to upgrade me, will they try to stick me with an older model, refurbished Hopper 3, or will they give me the latest and greatest new hopper 3? Also, I hear some talk of an upcoming Hopper 4. Is that for real? Should I delay my upgrade until it comes out?
