DH Labs Power Plus cable can be purchased in bulk for $6 a foot and Marinco male and IEC can be done for about another $25-$30 so you are just slightly higher than $50.
A very good cord (and gets much better if cryoed and burned in properly which need not cost a lot more and can be done later) which has been compared favorably with much more expensive cords.
On the "slightly warm" side of neutral, it is my cord of choice (I have 4 in use). In the past I've owned Cardas Golden, Blue Circle, LAT, XLO, the Asylum cord (Belden 19364) and others.
The DIY DH Labs is a very good cord. The commercial version at $200+ has some very good reviews online.
