Default Pontiac 8.2 4 pinion posi units.....ALL JUNK...

Sad but we all knew these were not rebuildable. Pontiac serviced these by just replacing the entire unit unlike the Chevrolets where they could change the clutch pack. I have gone thru (13) 4 pinion units i had here and 11 are junk / extremely wore out. 2 are marginal at best. Once again I have to buy (2) EATON 19674-010 Posi Units which have now steadily climbed to $695 plus shipping.
BEWARE of the trick wording on the Ebay Eaton "Style" units from China...Obviously not the same. I remember the Auburn Clutch style available years back but think those are a thing of the past.
Any other options / ideas?
Just bought an Eaton for a 68 "F" body 3.90 over the summer. I know these are proven and at the top of the heap.Just curious on others experiences.
