Well, I have an update! After much discussion, the overall package is the aircraft as-is, and...
A Garmin 430 WAAS, GTX 330, and GI-106A.
for: $16,000.
It's definitely equipment I want, and it's already installed and 337'ed. While, it's not the deal of the century, it's also doesn't seem way off the mark either. It's also firm. So, it's really in take it or leave it territory...
Leave it.
