fwiw I have an EDM830 in my plane and I'm very happy with it, had it for about 6 months now. Picture of it in flight:
More pics if you click the picture then follow the "avionics" tag. There are a couple of minor irritations with it but on the whole I'm very happy with all aspects of it.
I'm afraid this doesn't help with the EASA issues though. Americans have a hard time understanding why I feel blessed that we have the FAA...
