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?

£38 for 1m cable with sonar quest iec. Twisted 12? AWG Double shielded and occ copper.  I bought 4. They take 100 hours to burn in. Wish I had made this upgrade years ago. Transformed by system.
In my experience Power Cord upgrading was far more effective upgrade than a power conditioner (a PS Audio  Dectet) which I returned to the retailer. I have since made my own power cords. Not difficult, not expensive and big improvement to SQ.
