#1 seller for me is the fact that the bumpers are better replaceable cause they're attached to the joystick board not the button board. That was the ibiggest pain for me cause when they stopped working on my first deck I had to send it in, and they gave me a new one wiping out all the software customizing I had done. I can feel the bumper going on my current deck a few months ago, it only works if you press it a certain way and one small jostle could make it stop entirely again and I'll need to RMA AGAIN.
