One more tip (well, actually two):
If you want to learn to play a real piano, an electronic piano will do fine, so long as it has:
1. 88 keys;
2. Weighted hammer action.
That is true.
The Weighted Keys part is REALLY important.
However, 74 keys will work for MOST music, even Classical.
Unless You are going REALLY DEEP into Rachmaninoff or Liszt, or Someone else who likes the LOWEST or HIGHEST notes! ha ha ha!
Another thing.
61 keys: an easy carry.
74 keys: a Schlepp.
88 keys :FUGGEDDABOUTIT!
LOL!
