Second hand, pianos can be much cheaper than keyboards - while feeling more like a real piano than any of them..
Weighted keys and hammer action are pretty important. In my experience the only keyboards that really replicate this accurately are high-end pro keyboards like Kawai's MP3 or MP5.
Another alternative would be to hire an upright piano. (This would be my first choice, personally) I think it's pretty cheap and you can hire on a monthly basis. Also, that way if he changes his mind about learning piano there's no harm done, as it were.. (Is he planning to do music for matric, or is this "class" music?)
Presumably also, a school like Rondebosch High has a practice block where kids can use school pianos? That'd be the cheapest option I guess...
