I bought one. I already have the original version of the X-Arcade stick, and like it pretty well. I plan to use the extra space on the side to throw in a couple of spinners. I'll be a little odd to have one spinner on the far left, and one on the far right, but at least the controls won't be too cramped together to use. I also have a SlikStick, and using the spinner or the joystick on the top row are a little bit of a pain, sometimes. *shrug* I am looking forward to trying the trackball on this new x-arcade unit!
Later...
