I'm trying to decide between purchasing a lifetime series2 dual tuner and signing up for a 3 year (MSD) contract. I decided against the Tivo HD for now because it doesn't have MRV. With all the talk of the changes that will occuring with tv over the next couple of years I'm wondering if it would be worth it to purchase a lifetime unit. I know if I go with the 3 year contract I can transfer the service over to a HD model if the S2 stops working. I'm having a hard time deciding and was just wondering what others are thinking. Thanks!!
