If you don't care about COO ANY socket made in Taiwan and most made in China will be great - they will have good chrome, be manufactured well, and be finished nicely.
If you care about COO (US made) Craftsman/Danaher sockets will be the cheapest available, next being SK, and then after that you get into some pretty pricey sets from Proto, Matco, Snap-On, etc.
Let your wallet, and conscious do the talking.
I would not worry about warranty. Why? I put my Craftsman 3/8" sockets to 150 ft-lbs and past that and they are still ticking. I guarantee you that you probably won't ever break a socket. All the sockets I exchanged were done due to manufacturing defects and I did that right after I bought them. These are 1/4" sockets for Christ sakes.
You will lose them however.
