I'm not sure if this is the right place to ask, but I have a 2010 Macbook Pro 13" with 2.4 GHz Intel C2D, 4GB RAM and 250GB HD. I'm wondering what it's current value is? It has light cosmetic scratches but no huge dents or anything. I take good care of it. I'm thinking of trying to get either a 13"/15" i5/i7 MBP for myself eventually and was wondering how much money I could get by selling mine?
