There are lots of great expensive tools out there, but this one is a gem on a budget.  These cheap crimpers are usually sold as D-sub pin crimpers, but they’re perfect for .100″ header connectors.  These connectors (officially called Dupont connectors) are used all over the RC and RepRap world.  We use them for servos, stepper motors, thermistors, endstops, fans, LED lighting and just about everything else.
