fascinated with another musical instrument

I recently watched a concert aired on TV with my little musician in the making. She really enjoyed listening to the performance of an orchestra. I noticed that her eyes were glued more on one musical instrument - the cello. Cellos fascinate her since she thought it's the same as the guitar that she was able to hold the last time we went to my hometown for a short vacation. Definitely, I would not be surprised that one day she will ask permission to take short courses on a particular musical instrument. Whatever musical instrument that is, I just hope that we would be able to afford it. I guess I'll have to start looking around for ideas how much a cello, a violin, or an electric guitar would cost.
