I bought one at Tractor Supply, it was branded "Ditch Pig" and was about $70. I have used it at least 50 times with no problems. Even pulled out a stuck semi with it. Had the F-350 smoking all 4 on pavement.
7/8" seems like just the right amount of stretch for Jeeps. Bigger ones are too stiff.
I love mine for snow wheeling. You can hit it hard, like in your video, and barely feel the jolt, but you move with it as it rebounds.
I've seen lots of brand names for them, not sure if any are really better than the others.
