well if you have lost some confidense in it then i would buy a whisker biscut but if you are comfortable with that rest then replace it and make sure that problem with the screw doesnt occur again like tightening all the loose parts down but i currently use a whisker biscut and i love it i cant find nothing wrong with it at the moment but it hasnt failed me yet so i hope i could help a little with your decision along with the other guys.
