I have the cheaper version made by Titan (not Titan Winch). It's not made as well as the X-Jack, but it works. I used it a few times to rotate tires, but used it more times just to show it to inquisitive people that wanted to see it in action. It's nowhere near as steady as a Hi-Lift jack. It feels like your FJ is on a big balloon, and it's kind of bouncy and rolls around a bit. If you do a search for Titan Exhaust Jack I'm sure you will find pics and info. Actually, if you search for "X-Jack" I have a feeling you will find information that is even more relevant to your query.
Here's a pic of it back when my FJ was only a few months old.
