If you have to use component vid, may I suggest Tara Labs RSC cables. They're $300 for a meter, but can generally be had for around $225 or so. In a direct comparison vis-a-vis DVI, I really could hardly tell any difference.
Cheaper component cables, by contrast, failed pretty miserably compared to a good DVI cable.
