Where to buy good semi-cheap ratchet socket set in USA?

I had Craftsman sockets and now this smaller Kobalt set I got for half ton on sale a couple years ago. I love the case, size, and quality. Easy to grab and take along on any road or camping trip and stay organized. Only thing I would change is 6-pt for all, but these have not stripped yet. Lifetime warranty/replacement if I ever do break something and lots of Lowes stores throughout the USA at least if I'm traveling. I added a 3", 6", and 9" 3/8" extension that fits between the rows of sockets.
