I have an 89/B in my plane and had it installed a few years ago. It was
a requirement for IFR certification to have an annunicator installed in
the visual scan. The 89/B did not accomplish that or in the unit. Rules
may have changed.

Not so. The KI-209A contains its own switching relays and converter,
and can be driven by both the KLN-89B and the KX-155. The annunicator
can be made from a couple of push buttons and a few lights, and ought
to run a lot less than $950. Your FSDO will be able to comment whether
lights are needed at all.
