Experiences with MR6K-38 mid-height lift?

I've narrowed my search down... there are a few contenders for a budget "portable" lift for our '65 valiant (and probably my other cars). This is one of the top-two.

Any experiences? There is more than one manufacturer of what look to be this same lift.:

Here's one version: Workhorse Portable Car Lift MR6K-38

Thanks,
