Hi End Wii AV cable

Another video store closed near me. So, I'm streaming NetFlix through my Wii game console. Has anyone upgraded their standard Wii AV cable? Did you get a better picture and sound? What brand cable did you purchase? Is their a Wii compatible cable that does HDMI?

The Wii doesn't do hi-def. It's only 480p. I second the Monoprice component cable. I had one but have since gotten rid of the Wii since the kids never played with it. I bought a Kinect instead for them to not play with in the future.
Looks like I'll try the Monoprice cable. I have their HDMI cable in my AV system and it is excellent!
