On the other hand, I have seen guys do major damage with tools such as an impact wrench. The most important tool you have when working on a vehicle is your brain. If something doesn't want to unfasten, better to think about why, rather than just putting brute force to it.

And, quality is important in tools, if for no other reason than for your own safety. Case in point, I bought an inexpensive 3/4 tp 1/2 inch adaptor. Use a 3/4 inch breaker bar, and the adaptor sheared. No one was hurt, but it could have been serious when the resistance on the bar suddenly disappeared. Took it back to the hardware, and exchanged it for the brand name one I shoulda bought in the first place.
