My input would be the Dynon systems are hard to beat. Easy to install (from personal experiences). Very easy to operate (for the stick-ape in all of us). More features than even a control freak can use up. Great price (from sources other than AS). Can be used for IFR (with a back-up). NAV sources (GSP, VOR, LOC) can be put on its HSI from external inputs. Can monitor more about your engine than even Mark Langford can digest (not a knock to Mark, just acknowledgment that Dynon has superb capability). Optional transponder that can be operated from the SkyView panel (no extra unit in the instrument panel face).
MGL makes some excellent systems as well. Same basic functions, but different interface. Solid construction. The V10 radio is probably the best overall 5-watt transmitter going today, and it can be operated remotely. I have 100+ hours behind a Dynon D180 in my KR2 after 200 hours behind steam gauges. Great unit. IHS, Dave "Zipper" Goodman President, EAA-818
