There is always a chance that these cables (ZuPivot, Silver Dragon) are just Belden wire of some sort. Silver Dragon sure is a snazzy name for a cable as is the Silver Dragon logo shrink wrap. Don't be fooled by looks! 2 layers of techflex? Wooo, getting extra techy! Seriously, Belden is a great cable company and I use them for my DIY projects, but techflex is only for looks (unless you are using more than 1 cable and you need to keep them braided). I bet this is a great cable, but you could build one for $25 w/ the cardas plugs.*
*Please, if you are aware that this is not Belden, contact me, I will be happy to edit my post.
