If you have the money and your wife wants to buy a Tivo, GO GO GO!
I have been drooling over a Tivo for a long time. Yesterday my wife looked over at me and said, I think we should go get a Tivo. I immediately jumped up took the dog out and rushed my wife to Best Buy where we gladly handed over the money for our shiny new DVR.
You have to go fast because you do not want your wife to over think it and change her mind.
I acted quickly, and when we got home (after the 3 hours it took to install our new system) we enjoyed picture perfect digital recordings of some of our favorite shows.
