DISA can be rebuilt for 20¢. Find my thread showing exactly how. The plastic part that wears out can be replaced by some common 6-32 screw hardware and some heat shrink tubing. Literally better than new.

I found the thread.
My car I bought the aluminum/titanium kit which is amazing but when I needed to fix wife's, I took it apart and quickly realized I could just make the broken part from parts on hand.
