I have never heard of them? I did a dealer search and I was amazed at all the dealers! I cannot comment of them, but the Joystick looks pretty weird! I would really like to drive that thing and see just how it turns, I mean is it a true zero turn or does it turn like a tractor? It seems like there is a race to invent all these goofy mechanisms to drive and turn these Z's when the sticks are really the best way to drive em? I mean maybe they are more user friendly to older folks and wives and such, but to me the sticks are the most accurate and fastest way to maneuver a ZTR. Just my 2 cents I guess.
