I could believe a small number like 2000-4000. If these were popular and in demand computers, it'd be a different story... but with Amiga dead for well over a decade now, I suspect that the number of people in the world who still own and use Amigas is pretty small. Among people like us, these are great machines with real value. To the vast majority of the world though, they're just old electronic junk. I wouldn't be surprised if the same few machines are getting passed around among collectors and retro hobbyists. With many people being happy with 1200s or Commodore 4000s (not to mention older non-AGA models) I could believe that a couple thousand Escom 4000s would be enough to satisfy the market.
