Reverse Hyper?

Does anyone know of a way get a reverse hyper set up for a power rack that doesn't cost an arm,leg and soul?

Just so you know, all of those rigged up versions are nothing like the real thing. I've found no carryover at all..

I cut them out completely and stick to pullthroughs until I can get access to a rev hyper all the time.

That's what I was afraid of. Looks like it's time to put this machine on the top of the old wishlist.
