Replacing the screen on the Macbook is definitely easier than on the Macbook Pro (you listed a Macbook but posted in MBP forum). I speak from experience, having done both.
You need a lot more patience on the MBP because it's glued down and you need to gently work all the glue loose.
If you are detail-oriented and (most importantly) patient, you can easily do the screen replacement yourself. Follow the tutorial to the letter (
http://www.ifixit.com or other instruction site) and you should be fine.
I'd recommend giving it a shot, you can always take it in if it turns out to be too challenging.
Best of luck, let us know what you decide.
