The VP is a high quality gearbox. The little collets to fit different motor shafts are a big plus. So is the add-on encoder. Personally I would like to see all of our gear box suppliers incorporate an encoder on the input stage.

If you need a gearbox that fits the FRC motors, but is more robust (higher torque and shaft loads) than the Vex, look at Banebots products. They are heavier, similar pricing, and also very high quality. They also stack like the Vex, so you can purchase a couple different gear ratios with different motor input plates, and then stack to make the gear ratio you need. The Banebots work particularly well with a CIM motor.
