Caliper rebuilding

Im back with another project/thread. This time brakes, specifically caliper rebuilding. I just picked up a set of used calipers that look partially rebuilt, but the cylinders may need replaced. I ordered seal kits, but I noticed pistons are either out of stock or maybe difficult to find? Any advice on where to get them from?

Are the pistons REALLY that bad that they can’t be cleaned up?? Are they scored or out of spec???

I haven't actually broken them down yet, the boots just look hosed. I will reuse them if I can, but I was mostly just asking so I could understand my options.
