What's the price? I can't get the link to work.
You can probably get a lot more for your money just going to Home Depot and buying the parts seperately there.
Best Buy has some of the most outrageous network cable pricing I've ever seen.
If you have a
Graybar nearby you can pick up pre-made network cables for a fraction of what you can buy them at places like Best Buy and Office max.
Pre-made cables are also much better constructed than what hand made ones are.
[EDIT] is it the $90 kit w/ crimp, plugs, and 250' of cable? If so, you can buy 1000' boxes of cat5 for $50, a much higher quality crimper for $30, and the ends and wind up with a lot more for your $$.
