Better than the expensive ones. - Armaspec Fulcrum 90 Degree Short Throw Ambidextrous Safety Selector

This safety goes head to head with any high priced safetys. But this one in particular, I love, because of the protruding portion of the lever, which makes it very easy to engage to the on or off position. Also like how you can easily switch the levers, long or short (left or right side) to your liking.
