i have working wireless joysticks, but the sad thing is that im looking for them too...
But they shouldnt be hard to find, noone likes them, but i have no idea why, i am a big fan of wireless joysticks, they have some cheap ones going on e-bay, i would check there, i think theres like 4 sets right now, about 3 with boxes... Just thought it would help
Thanks
