Hi. I currently lease a 510 and a 301. I would like to upgrade to a 625 setup. I see that dish will upgrade me to a 522 for $100. Will dish give me credit for the two previously leased 510 and 301 receivers I have? I will need some wholes drilled and lines run, is that covered with the free installation? I know that my monthly cost will go up about $5 but I would like to know how much my upfront costs will be. Also, I am interested in the Video On Demand stuff being offered with the 625. Does the 522 have that capability. If not, do you think the Dish representative would give me a 625 if I have an interest in using the VOD feature? Thanks.
