Hey, I have a 13" MBP Mid-2009. Core 2 Duo 2.53 4GB Ram 250 GB HDD with NVIDIA Geforce 9400. 256mb At the time, it was top of the line 13". Now the bad: Battery Needs replaced. (1100 cycles) (about $120 DIY) Trackpad is pushed up, needs replaced (from battery bloating) (about $60 DIY) Optical drive is removed. Has some scratches, and minor dents. IF i were to sell it, i'd sell it just so i can replace it with an iPad or some windows 11" PC. Right now i just got a 15" MBP, so the replacement would be for portability, not for performance. Any idea what the 13" would be worth?
