I currently have a Tivo Premiere with lifetime service and an HD Tivo that has been renewing on the $99 a year service plan. I just got the Tivo email reminding me that my hd is about to renew for a year. I'd like to upgrade the HD to either a Premeire or the OTA capable Roamio. I'm looking for a "deal". I don't mind buying used or threatening canceling or paying up for a discounted lifetime plan. The easiest thing would be to pick up a used Premiere and replacing the HD on the $99 plan but last time I checked that wasn't an option. Any suggestions for a plan of attack to get a newer Tivo and service cheapest way possible? or alternatively get lifetime on the HD? Thanks.
