I bought my WhirlyJig (orange) several years ago for $600 used. I love it. Had my '63 Fairlane mounted on it with the suspension, minus engine/trans/interior and the screw adjusters worked perfectly, could rotate it with my pinky. Loaned it to a friend to do a '57 Chevy body and he didn't take the time to get it balanced and it almost crunched the roof on him.
Compared to not having the drop in the outriggers , it does drop the GC for any height of the car....again, compared to having straight outriggers. Its a very nice design. What makes me nervous about these things is having control when rotating the car. You really want the center of m*** on the axis of the rotation...or as close as possible to it.
