You're asking a grand for an ADF?

Good luck!

They're still pretty usaeful here in NC. Many ILS approaches here
require them because the IAF/FAF is an NDB. For example:

An approach-certified GPS can sub for the NDB here, but if you don't
have one you need the ADF to shoot this approach. There are several
like that in NC.

There are even some old NDB airways out at the coast.
