The only thing I don't like about buying the 3pk is that it is a discontinued model (which is why I can get it kinda cheap), but the new model(3PKS) does not have any upgrades that I find worth the extra cost to me. I have come to realize that the way a transmitter feels in your hand and being comfortable with it is more important than smaller functions, since it is your hands that are doing the driving, not the controller.
