I now have a 508 and a 510. I get charged $5 additional reciever fee and 1 dvr fee(the 508 is not charged). I want to get a 942. Can i pay $250 up front and then I get charged $5 a month for the lease? Do i get charged an additional $5 a month for the DVR on the 942, coming out to $10, or is it just a flat $5. Is the 942 lease worth it? Sorry if this is confusing.
