Wow, there were pages of gibberish here that was supposed to be a picture and an ad.
Anyway, I got the Champ and it's a fine inversion table (as far as I know because it's the only one I've tried). It's very easily taken apart and folded (I bought it gently used on craigslist) and fun to use. The first time anyone gets on it they laugh and giggle a lot. "It's like being on a ride at the fair" some kids said.
And we just keep it at 30-50 degrees for now. It's so stable with gravity control (you feel in control) you can take your feet out of the bars, hold onto the handles, and bend your knees or roll around. It feels weird moving all your innards upward, but it's probably a good thing.
But, after a few days the thrill wore off and it takes some discipline to make myself use the thing now, as you just lay there upside down looking at the wall. I keep telling myself to meditate, but never learned how! I've got to set up a light there so I can read while hanging like a bat.
The massage chair's a different story. I can't get out of that thing.
