Jerry,
I got the basic GRT Sport single screen 8.4 inch augmenting some other
traditional
instruments. So far I have been very happy with the performance, low heat
creation and low draw of 1 ampere. Reads easily even in direct sunlight. The GRT
EFIS also easily interfaces with an formerly bought and now installed GRT EIS
for Rotax 912S I also installed - the EFIS duplicating all EIS data graphically
(I bought 2 extra CHT sensors) so I see all 4 cylinders graphically represented
over time. Easy, straight forward solid construction. Excellent customer
support and real people technical support within minutes. Only product promised
to keep working when GPS fails or pitot freezes over (not planning to go there).
GRT has a comparison of autopilots on their site worth reading.

eventually did not go with them because, although very entrepreneurial, they
keep
changing the configuration and, worse, let you change it. I do not want to
go IFR with a configuration that is not stable and extensively fleet tested.
After 20 years in military avionics, I am very keen on configuration management.

search, I ended up choosing between Advanced Flight Systems and Grand Rapids
Technology. AFS costs more, and just got bought out by Dynon, so I am going
with GRT.

Also he recommends that you do not fly IFR with his latest software until
there is extensive fleet experience. They do not get as much publicity, but
I think that they currently have the best and most reliable products.
