Hello Don,
I am not anywhere near flying yet,but I thought I would add my two cents...
Check out the Blue Mountain EFIS light I was planning on the Dynon but after looking
at all of the units I am sold on the blue mountain product. The price diffrence
for the BM EFIS light is only a couple hundred more and you get a built
in GPS, as well as in my opnion a much higher quality unit. The Dynon is nice
but really does not compare to the BM EFIS.
Just my opnion...
Good Luck

No experience with Dynon or Grand Rapids. I do have about 50hrs on a Blue Mountian
EFIS one and an EFIS Lite as backup. They function well, are intuitive and
make flying the plane a breeze. It is easy to change parameters or make adjustments
as well as upload changes. The autopilot is a little too aggressive for
my taste but works well otherwise. The gyros do well in aertobatics. It was easy
to adapt to after flying steam guages for 30 years. Really have had no service
issues with it yet so cannot talk to company service but I really like the
unit. Have not even seen a Dynon or GR so cannot give a comparison.

I also have three of the GRT units in place with the EIS. In my
humble opinion, only the Chelton system is better, at twice the price.
GRT, interfaces to arguably the best AP (Trutrak) out there
for the money. They didn't try to design their own AP.
They also interface to the most widely used GPS/NAV/COM on the
market (Garmin GNS-430). They are still working on several interfaces,
namely the ARINC 429, but that will be out "when it's ready", not
shoved into the market space before it's tested thoroughly (hopefully
within the next month).
So if you are going to spend a whole crapload of money, you go
with the Chelton, If you want to spend half the money, you go
with the GRT.
I'm not sure the rest of the players really do have as tightly
integrated a system as GRT when you combine EFIS display (size,
sunlight readability, refresh speed), Engine Monitoring (graphical
EIS 4000), AP integration, GPS integration, NAV integration, Redundancy
(multiple AHRS, magnetometers, displays) and overall simple
design.
Also, the GRT units are light as a feather! As well as the
AHRS and magnetometer. Just look at the size of that Blue Mountain
box.
Of course, I've only said all of this to justify to myself how
much money I've spent. Your mileage will vary. I'm not trying
to start a "this is better than that war", I have builders' disease.
