Question re Keyboard to learn Piano

[purplerabbit]

So R wants a keyboard for his birthday. He wants to learn to play the piano and we don't have room for a piano in our house. So do I have to get an 88-key one for him to learn properly. I am confused by the array of keyboards and the different numbers of keys -- 61, 76, 88 -- and need to know what to get him. Suggestions?

Most pieces don't require anywhere near the full 88 keys, but I'm not sure what would be a good minimum for him to be able to play most stuff.
