I'm on a month to month contract with dish since my 2 year contract is over. I have two receivers, a 622 and a 322. I want to upgrade my 322 to a 622 or better yet a 722. When I call dish they tell me I have to go through a local retailer since I live in HI. I don't want to have to pay for my upgrade if I'm going to end up getting a new 2 year contract with it. Any thoughts. Thanks.
