just my 2 cents - go to flea markets or auctions, cheapest place to get tools (good ones). Sears is currently running sales everyweek on tools. It is also cheaper to buy a set than it is to buy them individually - at stores. At flea markets you can buy the one wrench or socket you need. At alot of auctions, you may have to buy a box of junk to get the two good wrenches in it.
My advice is to buy an extra socket set. Having had things break when you can't afford to have them break is more of a pain than shelling out a few dollars to have a spare set around. You could buy a 1/2 & 3/4. And how many times do you need to use two sockets or a wrench and a socket at the same time. I think its better to be prepared for the worse.
There is more than one reason that chinese tools are cheaper, and its not all labor savings. They can stamp "chrome" or "steel" on an item, and who knows, it may or may not be. It may have a chrome colored paint on it. If it breaks and causes you injury - try going after them. The fraud is unreal, and documented all the time. People just don't care and continue to buy them cause they are cheaper. Not everything made over there is like that, but if the normal set would cost you 100.00 and your paying 29.99, there is a reason.
Climbing off the box now, sorry.
