Answer to "Where to buy digitizer/glass"TF700 has higher resolution than TF300 so it will not work. Plus TF300 digitizer as thicker glass like while TF700 thinner plastic. TF700 has 3 different version as v.1 , v.2 and v.3 so be careful that got correct version. I have some touchscreen problem too, I haven't tried to fix it yet but I will , soon. It might be difficult to change and includes some glued parts to front bezel.
