I had an original version of 10 pin camera remote cable from FlashZebra for PW2, which worked well with D700 / D300 and PW2. After I found out the original cable did not work with Flex TT5 and D800 I now have, I found the newer cable at FlashZebra and spent $31 including shipping. Though I can not compare with PW cord, I do not see problems with built quality.
All my cables for PW system came from FlashZebra and I do not have any complains about the quality. I am sure it is better than my Nikon MC-36 remote control, of which rubber joints of the cables are deteriorating and exposing the bare cables after 5 years of use.
