Go very basic
Forget all this glass cockpit stuff, get the most basic C152 and learn to fly the aircraft. Navigate using a map and compass.
Only when you are up to flying with the basic equipment should you move on to the better equiped aircraft.
The thing to keep in mind is that the day the the electrics fail you wil very quickly have to fly the aircraft on "basic" equipment an without having a good level of training in this you will have nothing to fall back on.
I each time I go to work I fly with graduates from the magenta line kindergarden and when the FMC fails panic sets in because they have not the experience to switch back to conventional navigation quickly........... you are lucky enough to be asking the question before you start the training and are able to nip this problem in the bud.
