I want to purchase 2 hi def Tivo boxes but can't decide which ones to get. I currently have a Tivo Series 2 box and love it. I also am leasing a Scientific Atlanta 8000 HD DVR from Charter Cable and hate it. Please help me decide what to get. I want to be able to get in on the lifetime transfer thing too. But fear with the holidays approaching a better deal will come up, as they always do. This is a big investment so I want to keep the costs down if possible.
