I like the foot pedal set up, one less thing to do with your hands so you can focus on the weld. Pretty intuitive anyway, the coordination isn't a big deal. Works the same as a gas pedal, and I'm sure you know how to work one of those. :D
This is my thought as well. The only time I would use a hand control is if I'm doing some crazy out of position stuff where I can't get my foot on the pedal.
