I got myself a 3rd party component cable for the Wii. If your TV can output 480p, this cable is the ONLY way to go.

Of course you can't compare Wii's 480 with XBox360's stellar 720p - but hey, it makes the Wii games look a lot more sharper than the crappy composite. If you have a nice widescreen HD tv at home - you can junk the composite lah.

I wouldnt go so far as to say the Wii looks "GREAT" in 480p - but its a big enough jump from composite quality to warrant the investment if you have the right TV at home.
