 Buy a couple of flash chips in case of you breaking them, and to test different payloads. Furthermore, one could buy a proprietary chip just to debug the hardware.
 
 ROM-chip (eg.): Winbond W25Q16DV (Note: the image built from Libreboot needs to match the ROM size. Specifically, if you're choosing pre-built this must match exactly AFAIK)
