Cliff notes.

ESCO 3 ton stands: A+ Expensive, but worth it.
Harbor Freight 3 ton stands: B Cheap, strong, and amazingly decent.
Torin 3 ton aluminum stands: C+ Lightweight, small. Base is too small. Also $$$
MVP 2 ton stands: C- Convenient, cheap, and well built. But could self destruct.
Craftsman 3 ton high lift stands: D- Almost no redeeming qualities.
