Which DVR is best?

tivo logoFolks, finally I have decided to get a digital video recorder. However, despite all the information, I am having a tough time time deciding which one to buy. So my friends help me out and tell me which one is a good buy. I am looking for good value for money. It would be nice to get some user feedback. My wish-list includes spending as little as possible and also wifi support. And I would rather not pay any monthly fees to get the service!
