You might wanna check out brands like Avermedia or Leadtek. Oo mura na lang talaga. Kung internal tuner (PCI or PCI-E) mga 1.2K. Kung external (box), mga 1.8K. Ako I'm using Pinnacle PCTV Pro which I bought like 4-5 years ago. Mahal pa sila nun, lalo na yung brand na Pinnacle. Ok pa naman siya hanggang ngayon, it serves its purpose. Pero I'm tempted to buy one of those box tv tuners now kasi may additional input (for dvd players and game consoles) aside from the antenna/cable input. So you can play games or watch dvd movies directly on your pc monitor. I'm considering the Leadtek Winfast TV Pro 1680. With a box tuner you can use it even without turning on your computer. Kaya lang you cannot record tv shows with it ata (kasi the tv signal doesn't go through your pc), which you can do with internal tuners.
