The current state means you deal with “refurbishers” that mass sell used components (possibly fixing common issues at a micro-level), buy “broken” units yourself to harvest for parts or grab them off eBay et al. Sometimes the manufacturers do run extra production runs so you get new OEM parts. Or there is cross compatibility. I’ve covered a fair bit of the expense of my new Mac units by parting out my old ones.
