I have been an amature woodworker for some time now but I'm new to the scroll saw.  I bought this one because I thought it would have little vibration due to it's mass.  Was I ever right!!  Others have said that it has a small amount of vibration, but that doesn't do it justice; this saw doesn't vibrate. That alone has made it a wonderful tool for me.  I can concentrate on learning fretwork instead of wrestling with vibration.
