Willing to pay reasonable price for this unit....

I had one of those with a '515 I owned for a brief time. I also had the memory
unit.

That memory unit was the NDH-515 and only stored 24 frequencies. It was big!

Amazing how the technology has improved, the R8B has 1000 memories and I don't
use a single one!

Good luck in your search for the controller.
