Yes, I'd very much agree that they are useful.
There are two main kinds. One type is like the one David made, and I sourced second-hand from eBay, and they attach to the bumper mountings. I believe these are suitable only for a bare bodyshell, and of course it needs to be in solid enough condition that when you lift it on the two extreme ends, it won't distort. Using one of these with different shells is just down to altering the mounting points to suit each shell. Mine came from eBay and was used previously for a Ford Escort, but it wasn't difficult to alter the mountings for a HC shell.
The other type mounts onto the hubs, and is intended to roll a complete car. I've never been quite sure on those how you deal with fluids in the engine, gearbox and rear axle, but I imagine others have solved those issues. The hub-mounted one of course means that if you wanted to work on a shell that has no front or rear axle, you'd need to make some kind of adapter or temporarily re-fit those parts, so perhaps less useful if you're intending to weld where the suspension mountings are.
