Harbor Frieght
I bought one almost 5 years ago, when they were 2.5 ton.
No issues at all, and is actually better than a few I've had over the years.
My car sits pretty low and the low profile fits great under the LCA.
I've even made a couple of adapters that utilize the bolt on pad.
One is a L shaped 1x4 that I can use to get on the pan rail.
The other is in progress and will be an 8 3/4 holder.
