I fitted from a new build twin Dynon 10inch Skyviews in my aircraft and over the last 6years both screens have failed!...coloured vertical lines only shown! Each failure at separate times incidently resulted in returning the units each time back to Dynon in the USA for repair. Not good!
So be aware that although flying behind glass is much nicer and you generally fly with much more information at your fingertips it is not foolproof. You always need backups.
Personally if I were building a simple type Permit aircraft today I would probably just fit old fashioned steam gauges. When and if one or the other steam gauge fails it is then less of a problem/hassle and certainly not as big hole in your pocket!
