I recently replaced my Macbook screen after living with a half cracked LCD for over a year because I had assumed it was impossible to DIY and a hefty charge was inevitable. I followed the relevant guide on ifixit and found the whole process pretty straightforward. I would have grappled with it much earlier if there was more messaging out there that says "hey, if you have nothing to lose, and more spare time than cash, you actually can fix these things yourself", because you totally can! And you also get to feel smug about it afterwards because you hear so much to the contrary.
