You still need to shave the injection sprue bump off of the edge of the GameScience dice.
Filling the numbers is easy to DIY. Rub it with the flat end of a crayon and wipe the surface clean. This is how people did RPG dice back before Chessex.
Chessex and others automate both of these for you by dipping the whole die in paint out of the injection machine, then running it through a rock tumbler. The injection nub is removed and the only ink remains in the number recesses (or any flaw recesses).
Gamescience dice cost more for the better material. The plastic is stronger, more resistant to chipping and wear, which is required for rolling with sharp edges for years on end. They're actually lighter than chessex, and the plastic is not as soft.
