I've heard dish allows three hoppers on the same account. I've also heard you have to purchase the third Hopper. That's all fine and dandy. I will purchase a third hopper. My question is 1) How should I purchase the Hopper? Should I buy it from dish? Or should I purchase it off ebay or something like that? 2) In what manner should I go about activating the third Hopper? Also, about how much does the third hopper add to the monthly bill? Is it the same as a second hopper? or do they charge more for the third hopper per month?
