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?

Checking out their website I was unable to find the SE-1 model power cord at Art Audio Cables.
There are lots of power cords available used at very reasonable prices. I would suggest: Kimber, DH Labs, Zu Cables,  Shunyata, Supra, just to name a few. It pays to experiment.
You might take a look at Cullen cables as well. Brand new they are very affordable and well built.
