Wow, great aircraft with an even better panel.......and you're getting two of them! Our flight school is getting a DA40 with the G1000 in the next few months.
Two Garmin representitaves stopped by with a demonstrator model of the setup. I didn't have the chance to work with it too much, but from my experience, if you can use a 430/530 you can use the G1000. I think the reps said it was about a 5 hour transition period from "steam" gauges to "glass"
Incidentally, another instructor and myself just ate lunch today with a Cessna dealer. He dropped off a whole packet on the G1000 and some basic info on the 182 and 206. (pm me if you want more info)
I think the trend for GA aircraft will be towards glass cockpits.......... eventually.
