Any good aluminum floor jack recommendations?

Just a hint with buying cheap jacks ( of any sort )....replace the oil.
You see, at the factory where they make the jacks, they use the old hydraulic oil from the presses/stamping machines in the jacks, and put new oil in the presses.
I used to repair jacks/hydraulic components....so I saw this a lot.....as well as they don't clean them properly before assembly and swarf would get in the ball-valves, so the jack wouldn't operate properly.
