I currently have a 722 and 508. On the 508 they charge $7/mo. and are giving me a loyalty credit of $2/mo. for two more months, then I will have to pay the $7/mo. As you know the 508 is MPEG2 and is NOT HD. I'm thinking about buying a 211 and EHD, then selling the 508. Wouldn't the monthly fee be the same and other than the one time activation charge for the DVR, is there any disadvantage to what I am suggesting (any higher fees)?
