I have two HF jacks, the 1.5 ton mini aluminum racing jack Jeff has (often available for $60+tax with a coupon), I take the small one to AutoX or track days and leave the big one at home.
The one jack I bought, returned (unopened) and wish I’d kept was the Arcan 2-ton or 3-ton low-profile steel floor jack that Costco was selling several months ago. Was either $100 or $130, long, low-profile, and implicit ability to return to Costco anytime for a refund if something goes wrong. They don’t have it any more, but they are selling a different Arcan aluminum jack in the warehouses now. It’s $99, lifts more weight and higher than the HF 1.5-ton aluminum racing jack, and weighs around 50 lbs. But the minimum height is 4″, so if your car is lowered, or if a tire is flat, you might not be able to get it under the side jack pads.
I wasn’t sure that jack would fit under my (lowered) jack pads, so I just got the 3-ton HF floor jack for $89 (minus 20% coupon, but +tax), which goes as low as 3″ and as high as 18 or 19″. It weighs 72 lbs. Doesn’t go as low or as high as the bigger HF one with the foot pedal, but weighs less (that other weighs 93 lbs) and should be enough for me.
