[MD83driver]

After 2 some years getting 4FZ airworthy, I gave quite a bit of thought to avionics to come. My final decision was to buy the following:

Garmin 345 with Bluetooth.
Garmin GTN-750 used w/8130 from Garmin. Much more like an FMS like I am used to in the airlines for programing, not like a 530/430. Has all the airways. Avidyne Navigator will work well for that to, but did not find one at a fair price.
G5 DG/HSI w/GAD-29 /GMU-11/LPM to replace my DG.
These will be integrated with my Garmin 335 TXPR ADS-B out.

Will keep my ADF and DME. Cessna 485's will come out, looking for a SL30, at worst one of my KX175's will go in as a backup. Stormscope will stay for now. Will use an Ipad for ADS-B in and WX avoidance planning, not to stick my nose into it. Live Radar is the ONLY thing for that, but not in my future now.

And it is all about how you want to use your plane, not someone else.
Let the fun begin!
