Well I just bought my mom a new LG LCD tv, and we needed to upgrade one of the recievers also, so I called Dish to exchange a 510 for a 622, and since we upgraded one of our recievers already this year we cant do it again. So intead of an easy exchange the CSR said that we would have to buy it for over 500 dollars. I hate dishes stupid rules. Is there any way around this?
