I picked up this one when they had them on sale for $30.

I’ve had it for about 5 years and never had a problem with it, other than the fact that it’s 70lbs. I would definitely look for something lighter if you plan to ever take it with you. I only use it in my garage/driveway so wheeling it around isn’t a big deal. It will lift the entire front end of my Expedition with no problem.
