I would suggest Harmonic Tech Cyberlink digital cable for the money.
The Kimber D-60 and the Orchid are two of the best digital cables out there. I highly recommend the XLO Sig. series digital cables as well.
I have the PWD as well and since it doesn't offer a warm sound character, the XLO Sig. 1, 2 or 3 digital cable will be a better fit.
All the cables I memtioned above are below your $400 limit in the used market.
Good luck.
