I was looking to replace one of my 50' cords and ran across these that are all heavily discounted. All claim to be Made in the USA and are highly rated. I did see that a couple of people received the wrong cable shipped to them, but it was corrected, so I think that's just an Amazon mistake.
Ultimately, I decided on a lighter duty cord for my needs but being 100% copper and US made, I wanted to share. Good luck!
