I would not say the owner is a jerk. I just feel he is too high pressure. With the New Yorker attitude added.... He may scare some. He seems to know his stuff. There is really only one reason I didn't buy from him. He will let you turn on the vacuum... But he tells you NOT TO VACCUM! Excuse me.....you want me to pay 500 or more but I don't get to try it. Next I will go to the car lot and ask to sit in a running car. But not drive it please. I don't get it. I liked the machine. You lost me at that point. Sorry sir
