$100 component video cables worth it?

[egads]

I was in BestBuy the other day looking for a set of component video cables. All they had were the Monster brand cables, and the cheapest 4' cable they had was $50USD and the most expensive was well over $100 USD.

Are the more expensive cables worth the extra cost?
I've seen several sets at other places that run about $15USD and look to be nice cables, i.e. gold contacts, double shielded, ...

Thanks...
