I love the AC Hydraulics jacks and sell them through my business....see http://www.ultimategarage.com/acjacks.html
. I'm not crazy about their low rise lift....there are much better ones on the market that allow full undercar access like the Nussbaum show below.
The twin piston design eliminates the crossovers between the lift platforms and you can easily do an exhaust or clutch replacement with this. Its also portable, even at a hefty 1200 lbs.
I own a business that specializes in the design and outfitting of high end garages and workshops....I'm always looking for new, quality tools and equipment to use in my projects.
