How Convenient: 3 ton floor jack?

I have had expensive name brand floor jacks that crapped out early in life. I bought the steel 3ton horror freight for use in the shop on the trucks, and an aluminum 1 1/2 ton to carry to the racetrack. Both work perfectly. I can still replace either for a third of what the name brand jacks cost me. Harbor fright sells some garbage, but their jacks have a good rep, at least with me.
