My 40-year-old Craftsman 1.5-ton, actually made by Walker, bit the dust again last year. For the price of a rebuild, I could have bought almost three of the yellow and black Harbor Freight 3-ton jacks, but I cheaped out and bought just one just to see how long it would last. It seems to work about as well as the old one, although it definitely looks cheaper. It sat through a 2-foot-deep flash flood about 6 months ago, but I shot it down with WD-40 after the water went down and so far it's still working.
I have one of the HF long-frame jacks mentioned above, and while it works great and lifts way higher, it weighs so much I have to be seriously motivated to actually drag its 130# carcass out unless I absolutely must.
is the yellow one, often found on sale for $10-$20 less.
