Shunyata Ethernet Cable - Used Delta or New Theta?

[NoRust]

I have read all the recent info posted here on the Theta internet cable and its been very informative. However for those of you with experience with Shunyata ethernet cables I have a question to ask. I have the opportunity to buy a lightly used Delta ethernet cable for the mid $500's or a NIB Theta cable for $500. Thoughts on which one to go with?

What did you end up deciding to purchase and how does it sound?
