They're under $50

So my cousin was asking about networking computers together. I sent him a link to some hardware, a cable/DSL Modem router hub combo. Off of the practicallynetworked.com site, I found my router. I bought it new for $120 or so. They're going for under $50 now! I know computer hardware drops fast, but man!

Of course, this still begs the question: Why are cables still so expensive? Shouldn't they be pennies a yard now instead of $8?
