We've had the debate over what brand of tools to buy on another forum that I'm on. I own mostly Craftsman tools but I also have tools from Snap-On, Mac, and almost every other tool manufacturer.
If you have limited funds, or even if you don't, I would buy Craftsman. If you purchase only Snap-On tools you will have only about half the tools in your tool chest than if your purchased Craftsman. What good does it do if you have spent all your money on the most expensive tools but don't have a tap and die set, snap ring pliers, gear pullers, etc when you need them.
Craftsman has a lifetime guarantee on their tools and it is a lot easier for me to take a broken tool back to a Sears store than it is to chase down a tool truck. You can easily get replacement of a broken Craftsman tool on a weekend , after hours, or even out of town. Try call a Snap-On guy at 7:00 p.m. on a Sunday.
If you have a particular Craftsman tool that you use a lot and it breaks a lot, I would buy that tool made by Snap-On, Mac, etc. I have not had this problem however. I have read that impact sockets made by Snap-On are not covered by their lifetime warranty. I was in Harbor Freight Tools the other day and a guy brought back a broken impact socket and the store replaced it no questions asked.
Don't get me wrong, Snap-On tools are made very well but a lot of the money that you pay for them goes to the high overhead to pay a salesman, to insure the tool truck, fuel the tool truck, and market the tools. I still have some Craftsman sockets and wrenches that my grandfather bought in the sixties, that he used a lot, and are still going strong.
Listed below are links to hand tool manufacturers and distributors that you might want to look at.
