I've sequestered ~800 pieces of Lapua brass in 243AI and 308. The sequestered lots have all experienced case-neck cracking and I've also seen some significant vertical stringing in rifles that don't string new brass. The cases all have primer pockets that hold primers just fine. So, in this time of very low component availability I bit the bullet, bought the AMP, figuring that resurrecting those 1st 800 cases covers at least 50% of the acquisition cost.
Beyond the 243AI and 308 Lapua cases that are of known loading numbers, I have a hodge-podge of multi-loaded cases in 223Rem, 22-250, 243Win, 25-06, 270Win, and 300Win that I inherited from my dad. Currently they're all sequestered by brand, but there's no telling how many times any of them have been loaded. I figure I can clean, anneal, trim, and FL size them and have predictable results. If this winter gets much longer I might even separate them by weight.
I considered the AMP purchase to be "cost avoidance" rather than extra expense.
