What really sucks is that if you go through all that expense and effort then
sell the airplane, you won't recover 1/2 of what you spent. It really goes
to show that with all things considered, its a good idea to buy an airplane
with the best avionics you can find.

This was the biggest reason that we didn't opt for a new 430 in our Aztec.
We already had a KLN89B installed, but hated it. We were all 430 pilots and
could run it with our eyes closed. But we chose to buy a KLN 94 because the
it was just a direct swap for the 89B, no install required. Although not as
user friendly as the 430, the $7200 that we saved sure goes a long way
towards having to look at a smaller display and punching a few extra
buttons.

I feel for you.
