A lot of it can be made if you are handy in the shop with
fabricating. I'm fortunate as I have a mill and lathe and have
duplicated tools based on the pictures in the manual or from
pictures on the internet.
Usually the original tools bring a pretty good buck and since
they are special, not generic in their use, you may only use
an expensive tool once, where it will lay in a dusty drawer
till your kids donate them to Goodwill after you're gone.
