The hi def $1000 TiVo that is currently available is a DirecTiVo, so you'd have to go with DirecTV to get it. That said, a standalone TiVo box is not going to give you quality. A DirecTiVo will, but a standalone won't. However, it does let you do all the really cool stuff, and frankly, I don't need to watch CSI at mind blistering levels of detail...
