Present for my sister

I'm 19 years old and have an older sister who is very talented in music, just as much as I am.

I was planning to buy us a real keyboard because our last one got damaged and since then we were playing on computer keyboard.

I would really appreciate this because I really love her and she deserves it very much but unfortunately I can't buy it to her because I am student so all money from my job ends up at my faculty.
