Hello Patrick,
Welcome to the community. I am a new member as well and I am looking into purchasing a Bonanza myself.
I asked the same question myself and I have been doing a lot of research regarding avionics.
What is better than the G-1000 is the GTN750/650 combo. Touch screen with lots of new features. If you can combine them with a G500, and and imbedded transponder and autopilot, you will be all set. The whole system will cost you around $60k.
Adding a JPI 900 will be the icing on the cake.
I love Martti's setup but personally, I would chose to put the new aspen stand-by instrument (attached picture) and place it right under the G500.
I will only install the round dials on the co-pilot side.
Just a thought.
Congratulations again.
Cheers
