Looking at these, wonder if anybody knew of anything better. Thanks!

The Jegs units look good, but it looks like folks are 50/50 on having to return them. No parts available.
I've got a set of the older Harbor Freight ones (Red) and they work well, the mechanism to switch between raise/lower is a bit complicated, but that appears to be fixed on the new style ones.
A recent catalog for Harbor Freight showed a set of Daytona ones that are coming out. I haven't seen them in stores or even on the website yet. The nice thing is they offer a storage rack for them just like the Go-Jacks.
When I was researching what to buy a few years ago there were a lot of complaints of leaks and other issues on the hydraulic ones so I stuck with mechanical.
