Whenever I am in a situation where the integrity of a tool will have a direct impact on my quality of life, I do not skimp. I figure I put enough money down on a truck that barely runs, I can put down some money on quality jack, jack stands, etc.
Most of my HF tools are pneumatic: die grinder, cut off tool, air hose/fittings, impact wrench, and some more that I forget.
Impact wrench was a total bust, and I had one fitting break off. The broken fitting was a mess because there was nothing left to grip onto. Ended up buying a HF extractor set and it worked perfectly.
