Next club purchase...

Our club currently flies a 172R and 172SP as trainers and a Diamond DA40 as
our 3rd plane. We've put tons of students thru our 172s and are finally
getting some good usage on our Diamond. We've started "long distance"
planning on our next planes. We'd like to get a good low wing trainer like
an Archer and we'd like to get a high performance plane to get complex
ratings. For the complex plane, we're thinking we like something that can
do 150kts or better that we can do a nice panel upgrade in - say a G540
stack and some other upgrades but still something that the insurance
wouldn't kill us... As we're near the mountains, turbo would be nice but
would incur some other problems with training, etc. That said, we were
leaning towards a Turbo Arrow III... Any suggestions?
