There is also the new Avmap EKP 5.
Unfortunately, all the large-screen units (the above, the 696, etc) have a battery life of under an hour, in reality, which is not great for the loss of electrical power scenario.
Regardless of details of map data I would go for a big unit over the Garmin x96 anytime. I have a 496 in the yoke (as a backup, and for its audio TAWS function which does work very well) and the map is too tiny for flying with, if this is to be your only GPS.
