I started to learn the piano alone the 17 december and so far my 61 keys have been enough, even tho the more I learn the more I notice some piece sounds either crap if you must adapt to 61 keys, but it should be enough for learning purpose.
For 400 euros you can find a great 81 keys/yamaha touch/midi tho;
