As a former professional mechanic for 25 years I probably have more in tools than I do in my house. I have a lot of the major brands, Snap-On, Mac, Craftsman, Matco, and several others. I've bought a lot of things from both NT and HF but most of the time it was what I consider throw away tools. These were the ones I would cut or weld on to make a special tool for doing a specific job. I've both good and bad from both locations. I'm a firm believer in you get what you pay for.
I currently have a HF floor jack that I got 5 or 6 years ago and it's still working just fine. It's seen quite a bit of use over the past two and a half years. YMMV
