I have the SS screw kit from RCScrewz. These guys are real professionals, they'll take good care of you! I think the SS screws are much better than the stock screws. I had to do some clutch work, and stripped all 4 engine mount screws. After upgrading to the SS, they don't strip at all. Also, the SS screws seem to thread MUCH better into the plastic than the stockers. Hope that helps!
