Electric or Digital Piano is a good choice. Here are some key points you need to know:

1. Go for the most number of keys: 88 keys is the standard.
2. Hammer-Action or Weighted Keyboard is very important since most training are traditional, like the Hannon Exercises which includes proper hand gestures, positions, etc. Here for more Info.
3. Metronome Feature is also very important. But no worries, almost all e-pianos today have metronome installed on it.
4. Velocity Sensitivity - the harder you press, the louder it sounds.

NOTE: BEWARE OF THE CONTROLLER KEYBOARD Unless you are familiar with it and knows how to use it, then go. But learning how to use it has a lot of technicalities that you should know. It is not a kind of "Plug-and-Play" keyboard.
