OK...awhile back I asked if Tivo was all it's cracked up to be, and within hours had dozens of you swearing that indeed it was. A common theme was "I don't know how I watched TV without it."

Well, you've never steered me wrong before. The better half has expressed an interest in Tivo as well now. So I'd better jump quick before he changes his mind!

The question now is...which model to buy? Where to buy it? Are there any "upgrades" etc I need to know about?

Thanks!
