Dont overpay, but this isnt an item where price is the sole consideration, although theres not much correlation between price and quality. Its very, very easy to do a crappy job of crimping a cable and have it cause you a bunch of headaches for a long time.
When I used to do network stuff, any time we had a customer with lots of problems it was usually because they went cheap on the wiring or had someone come in on the side to make patch cables to save a couple of bucks and the guy did a lousy job.
Once I bought a handful of the cheapest 2' blue network cables they had at fry's. Loose bin items, really cheap looking.
Over the next 3 years I had weird intermittent problems. I swapped cables around, tested power, tested for ground problems, changed network cards, etc.
Turns out that every one of the blue cables had poor crimps. If you wiggled them a little they'd lose contact. And of course I was using them to connect the cable modem to the router, the router to a couple of other things, and my tivo's to the wall plates. And they'd intermittently lose the connection and then get it back again.
I recommend an inexpensive but brand name cable, with a molded boot instead of a bare cable or one with a slide on boot.
I've had good experience with Siig cables. Not too expensive, not too cheaply made.
