I Like them.
lightweight, compact and more reliable than the vac gyros they replaced.
I wear bifocals and have no particular issue with reading the ribbons.
nice TAS and W/V indicator.
I prefer the single pfd install with remaining 4 primary instruments and elec sby ai in preference to the two unit install. have used both, single unit the go in my opinion.
integrates well with Garmin430.
good support both locally and from the factory.
G900 (aka Garmin 1000) not without its issues! also $$$
the G500 is another option to consider.
Honywell 840 takes up all the 6 pack space and has very similar info on display, just spread out more so the old farts (other old farts that is) can read it through their $5 reading glasses from chemist warehouse. I heard that it is to be discontinued, even before it is continued! good riddance.
