Couple of Notebook Questions

1. My screen has started to play up in the last week. Sometimes the picture goes altogether. Am I fucked? Will this just get worse? What are we talking about $$$ for a replacement screen (if it's even possible)

2. Does anyone know of a good website that does Notebooks that are slightly older. I.E. Cheap!! I need to possibly replace this one for the Mrs (while I get myself a nice gaming desk top).

Thanks to anyone who is in the know!
