Worth the extra cash - Meprolight USIT Universal Sight Installation Tool

As a gunsmith for the last 10 years I've managed to destroy 3 other sight tools ranging from 80 to 150 dollars. The investment in this one is considerable but after figuring it out and using it on both front and rear sights of various manufacturers I'm convinced that it is the last one needed.
Pros: Easy to use
Cons: Expensive
