Guys, I need to get an external 27" monitor for my 2008 1st gen unibody 15 inch MBP. The latest thunderbolt is not an option because I don't have a thunderbolt port. I will use it primarily for watching movies, tv shows and doing some image processing work. I'm flexible with price, but I'm in college so cheaper the better. I want it to have decent quality so that it lasts though. Thanks!
