X51 Laptop Screen damage

Question

the Phillips 12.1" XGA TFT LCD screen has been damaged probably from a fall and showing black spots and cracks. Currrent price of this laptop new is £400. Is it worth getting taking it to a shop to repace the screen or should i buy a replacement screen and try and fit it myself? How much will all of this cost and where can i get the Screen from? Your advice and help would be appreciated. Thanks
