DIY PCs

I am thinking about upgrading my system power cables.  First off, I should confess that I am an objectivist and a cable skeptic.  That said, I see nothing wrong with a little bling in the cable department.  I don't think any of the present PCs are stock, they are lab grade molded connector types suitable for lab test equipment.  I will need four PCs: Pass INT-150, Oppo UDP-205, and 2 x ML Montis.  I will most likely go DIY and would like to spend around $50 each.  Any suggestions?  Thanks in advance for your replies.
