Problem is you can't replace the digitizer screen. I have tried 4 times now with screens from different vendors. the best I got was a temporary working iPad that soon turned into the ghosting mess we keep reading about online. Lots of wrong/bad info all over youtube from people who don't know anything. I think Apple has something in the code to prevent third party screen replacements.
Maybe ifixit could be honest about what's going on and chime in?
