I've seen one on a dealer lot. Only thing I know about them I didn't like was not being able to make sharp turns. They are limited when it comes to turning. This one was anyway. Don't know if it's been sold yet. May still be on the lot.
I just bought one. Its easy to operate, has lots of power, but finding parts is a pain in the butt. I haven't had a problem turning, but I have lots of room so far. So parts is my only complaint.
