Solid core power cords under 300$ - List of manufacturers ?


I would like to try a 2nd hand solid core power cord under 300$

What are my options?

I know following manufacturers:

Audioquest (Copper)
Cabledyne (Silver)
Nordost (Silver plated copper)

DIY is also an option for me.

You need to be careful with solid core PC's. Too much bending can lead to wire fracture.
jea48 - I applaud your efforts, but NEITHER of those power cords have solid core conductors.  I know you were just trying to be helpful...
Zuio - there are VERY few solid conductor AC cables out there that I know of and certainly none of the 3 you asked about are solid conductors either.  Can I ask why you want solid conductors?
