I'm not sure whether your parents are buying it for you, or they are just telling you what to do with your own money (some parents are like that).
If they are buying it for you, and your sitting on $2300 I suggest you do what I did. Have them give you the money for the computer they are willing to buy you, and then use your money to pay the difference between the macbook and the macbook pro. Example...my parents decided they would get me a black macbook for college. I decided that since I do a lot of work in Final Cut Pro, Aperture, and Photoshop a macbook pro would be better for me. So I asked them if they would just give me the $1400 for the macbook and I will spend the extra (about $500) and get the macbook pro. Worked out well. I suggest you try that.
