You can purchase an aftermarket "grade A" screen from several places for around $400-450. You need a LM270QQ1-SD-E1. You can also use LM270QQ1-SD-C1, LM270QQ1-SD-B1 or LM270QQ1-SD-A2. The C1,B1, & A2 won't be as bright as the E1 however. I can tell the difference between an A2 (the first generation) and E1 but I can't really tell the difference between the B1/C1 and the E1 when it comes to brightness. I also can't tell the difference between "Genuine Apple" LCD panels and the aftermarket ones.
