If you just want the best joystick ever you can buy this
(well, another; this is mine and arrived yesterday, just like another I've got), but I don't want to start a war about joysticks...
Mine is hand held ("and-held also handˇheld (h nd h ld ). adj. Compact enough to be used or operated while being held in the hand or hands").
This joystick must be heavy, if not you would need the suction cups.
