Having flown a few hours in Nanchangs and Airtourers I would definately invest in a Nanchang. The Nanchang is a complex aircraft to start with but once you get used to the systems you wont look back. If you do decide to go down the Nanchang path let me know as I can put you onto the right person to talk to. I also wrote an indepth feature on type ratings on nanchangs and it explains type ratings etc. Its in the latest Aviation News so its worth a bit of a read if you are interested.
