Need recommendations for inexpensive power cord


I’ve never used after market power cords and am considering buying a couple.  I have some questions:

Considering the astronomical price power cords go for, is there any point getting one or two in a lower price range?
At what price point do power cords start to make a difference in your system?
I have two monoblock NuForce class D 160 watt amps.  Is this where they should go? 
Can someone recommend an inexpensive power cord that can make a difference?

Make your own ,
Buy Furutech plugs, IRC connectors and bulk power cable,
You'll get one of the best for the cost of a lesser pre-made one.

@rvpiano what power cords are on your Dac and Transport?
While we are at it (if you don't mind) which Dac and Transport are you using?
I have stock power cords on the DAC and transport, but I’m plugging them into the Isotek power conditioner with the Elite power cord. 
Components are the Schiit Gungnir Multibit DAC and the Cambridge CXC  transport (or sometimes the Oppo 105D used as transport which has good synergy with the Gungnir.)
