Robin:

I basically did what you suggested except I chose a garmin head rather than
the king head. So the extra parts I'm getting are the garmin head, the
KN-75 for glideslope, and an AmeriKing annunciator/switch. And you're
right, that does add to the cost, but everything included I'm still about
$2K shy of a new 430 install. I can't remember if I already mentioned this,
but I looked into the used 430s and couldn't find a 14v unit. I was advised
against using a 28v unit with a converter because apparently the converter
fails often.

If anyone has any experience, good or otherwise, with one of the 28v 430s
with a converter, I'd like to hear about it.

With your setup, if you want to use MD-41, you still need a KN-72
converter to
convert KX-175B's composit NAV to right-left for MD-41, and you would not
have
GS nuless you also get a KN-75 GS receiver.

If you want to share a CDI for both KX-175 & GPS, KI-209A is your best
choice
because KI-209A has built-in converter & relay switching for GPS/NAV
signals.
You still need a GS receiver like KN-75 to get ILS, and
annunciators/switches
to control GNC300's arm, hold functions as well as switching KI-209A
between
GPS/NAV signal by grounding a wire from KI-209A.

All these extra hardwares and installation make GNS430 a batter and not
much
more $ choice. Been there & done that with KX-125, KN-75, Trimble 2000,
KI-209A, and MD-41 (I get GPS on both KI-209A & MD-41). I did my own
installation so I saved by using used first gen GPS, but if I need to pay
someone to install for me, GNS430 with single CDI will be my choice.
