Since I see lots of opinions on laptops here, I'll throw in my 2 cents..
Asus laptops are/can be some of the best laptops. I highly respect them. I would assume that you just happened to get one from the bad batch both times.. Someone mentioned Acer, I HATE Acer with SUCH a burning passion. And Lenovo..well, you could do better, but they aren't terrible. Don't shoot me for this, but I'm kinda partial for Dell. It's very likely that it's just because I've been around them all my life and know everything about them, it makes it easier for me to know how to fix them. Anyways, I'm gonna stop ranting about this and see what people say about my opinions.
ON TOPIC: Usually laptop screens are between $50-200 in US currency. The replacement process is much different for every brand, however usually you can do it yourself at home pretty easily. Just remember to be very careful with the wires, and don't use your bare hands on them.
