Hello everyone, I am looking for an external display to complement my Early 2013 15R MBP. A co-worker of mine has a mint condition "lightly" used Apple 30" display. Bought 3 years ago. I have seen the display and cosmetically it looks perfect. She only wants 400$ for it. Good deal? Things to look out for? I believe there is two models correct, how can I tell if this was the last one made? If the bulb in the LCD were to die can I replace it myself? I was considering the current TB display but with just USB2.0 I figured why not have essentially the same thing and just go bigger with the older 30". Thanks!
