I've had several of the 3 ton Pittsburgh (Harbor Freight) jacks. None were low profile or aluminum. They've all been decent for the money ($68 out the door at the parking lot sale about five years ago). I decided I wanted an American made jack so I bought a 3 ton Hein-Werner. It's an awesome jack but it's about 50% larger than a standard 3 ton jack. It was expensive. I thought I was buying something similar to what I had but when it showed up on a pup tractor trailer with a liftgate I realized that wasn't the case. No regrets. It's American made and will outlast me.
