Best (portable) TV Tuner device

[TRDCorolla1]

What's the best portable TV Tuner card out there? I'm thinking USB powered since I can take it anywhere and use it on my laptop or swap work/home desktop PC.

If any of you have one of these or know of a good, reliable brand, let me know? I'm looking to buy one within a couple of weeks. What are some popular models?

No one knows? With all the computer junkies on here, you would think at least one person would have knowledge in regards to this topic.
