Hey all, so I have a tivo series 2 thats only single tuner with lifetime service. Have been renting a tivo from RCN (premier 1?) and its great but I can't really afford to rent it anymore lots of downgrading so i'm looking to buy a series 2 with a dual tuner and/or potentially trading my tivo2 single tuner w a fee for a dual tuner of some sort so I can downgrade the cable but have a dual tuner tivo... once you have a tivo I guess you can't go back hah. So questions: is the series 2 single tuner w lifetime service worth much? anyone selling a dual tuner tivo w/ lifetime service thats not expensive?? Thanks in advance!
