This will be my first DVR. I don't know whether Tivo or ReplayTV is better, but I'm willing to try either.

I'm looking for an inexpensive entry-level unit (40-80 hr?). It will be used with regular analog cable for right now. Does not need to be able to update over broadband or anything fancy like that. If anyone wants to upgrade their DVR and is looking to get rid of an old one, let me know.
