AOPA had a pretty good article about the DA40/42 a few months ago.
I guess there was an instance of a complete loss of power of one in Europe when power cycled to the FADEC for something like several thousandths of a second, but it was enough for both motors to fail and kill the occupants. Don't remember which motors they were. Supposedly the newer ones are better, but I agree that the Baron is a better plane. I loved my 20 or so hours in a Colemill BE-55.
