Question : Problem: laptop screen repair

We have a Dell Inspriron 4100 Laptop... Xp, something accidently fell on the edge of it causing about a 1 inch hole in the screen.  The laptop was purchased used.. researching the price of a new one, they seem higher then what we paid for the laptop.
My questions
1) Can we take the screen from ANOTHER laptop and put it on this one? I am obviosuly NOT a hardware person....so its a thought.  I THINK its an XGA+ screen but not 100% certain on that

2) What does it mean when people have blemished screens... these are a little cheaper- I found one for 125--which is like 1/2 of what I paid for the laptop.

Thanks

You may be better off just purchasing another used Dell Inspiron 4100.  then just transfer the hard drive from the old one to the 'new' one.
