I hated my Mag-Stik Plus, While the concept rocks, the throw was terrible, Couldn't be happier with my other ultimarc product though which is the u360.. However mine is mounted on 3/4'' wood and I feel that my u360 sits to low. Even with the 10mm longer shaft that Andy from Ultimarc offers it's still not long enough imo for those of us that don't have metal panels.
That being said get a u360, and have someone cut you a custom shaft, get a restricted "circle" plate on the bottom and the joystick is digitally restricted with maps, hooks up via usb.
