Swapped mine out about a year ago. I wouldn't call it hard, as long as you have detailed DIY instructions. Lots of small screws and tiny connectors, so it does take some patience. Small fingers (mind aren't!) are definitely a plus. The real booger is putting it all back together and seeing that the image on the screen is shifted left or right, and you can see a black strip on one side. There are tiny adjusters on the back of the board to calibrate...
