It seems to me that if there are no more child pages for a page, then the page name should be like this:
mypage.com/Products/High_Powered_Piezo_Electric_Ultrasonic_Transducer. html
instead of
mypage.com/Products/High_Powered_Piezo_Electric_Ultrasonic_Transducer/High_Powered_Piezo_Electric_Ultrasonic_Transducer. html
The url gets overly long!
