Tivo/DVR/PVR is so great, I could not go without one anymore, got my first one about four years ago. I still contend they add hours in the day because you can go run an errand, come home with the game (or whatever) half over and you just about finish watching the same time as the live broadcast anyway.

Up here we can rent them for about $20 a month but I just bought both of mine up front.
