Why purchase a cheap set to supplement a good set? Older USA Craftsman socket set are just fine. My main set for the last 13 years has been the 4 drawer, red/black blowmolded plastic case set. It's worked very well and done everything I wanted. And the raised panel wrenches also worked.
Are there better? Absolutely. Have I upgraded? Yes. I have purchased better ratchets, wrenches and now I am working on better socket sets. And that's my point. Why would you want to go cheaper and possibly less quality? Williams USA, SK, Wright (especially wrenches), and Armstrong (for ratchets) are all good brands and a big step up in quality. If money is tight, save up and buy a little at a time. Or buy a good 3/8's set, then 1/2 and then 1/4 set.
Right now, among other tools I am purchasing, I am putting aside money to buy some SK sets like this -

The ratchet is good but not great but you get a lot of quality sockets for a very good price. Get an Armstrong locking 3/8's ratchet and you have a nice set.
But in the end it's your money to do what you wish with it.
Good luck either way.
