For what it is worth, I was able to go walk around the warehouse while selecting my kegs. He said that post washing he hit them all with pressure.
He let my friend and I just pick the ones we wanted based on appearance while he went and did something else. There where thousands, no way he hit them all with pressure anytime prior to our arrival. Every single one I selected (based on cosmetic appearance) let out a nice healthy hiss when pulling the pressure relief valve. I know they could still pass this test and have slow leaks; but my point is I think your chances of getting an unrepairable keg are pretty small.
