For a home machanic, Craftsman tools are hard to beat. And I have beat an a few over the years, and have never had a problem getting a free replacement, some with upgraded features over the original.
I once shattered a 24" long 1/2" breaker bar by using a 4 ft piece of pipe as a handle extension and standing on the pipe. The guy at Sears laughted and said I must be pretty strong to break that bar, Then threw it in a draw with other broken tools and told me to go pick out a new one for free. Gotta love it!:wub:
I would recommend buying a small mechanics set of about 300 pieces. That will include both metric and SAE sockets, combination wrenches, allen wrenches, screw drivers, pliers , etc. That will cost about $300. You will also need some specialty tools like torque wrenches, and vehicles specific tools. Some specialty tools are used very infrequently and you are better off renting them on the rare occasions that you may need them.
One of the most overlooked tools to by for a home shop is an air compressor and some basic air tools, like a 1/2" impact wrench, 3/8" ratchet, air hammer, tire inflator. These tools can really speed up your maintenance jobs.
You will also need a good floor jack and at least two jack stands 4 would be better.
As you can see, over a few years you can spend a lot of money on tools.
I was in Sears tool department and once heard a little ask his mother "What all this stuff was". His mother said it was "A toy store for daddy's" :lol:
